Krucifax:
My fellow Nigerians dey talk. What of the uncountable numbers of Nigerians stripped naked, beaten and burnt to death by their fellow Nigerians inside Nigeria? Examples = ALUU 4,The female pepper stealers, etc etc. Whilst it is wrong we have a far worse record of inhuman treatment to others.

You're right, its the pot-kettle thing. These are the same people that will bring tire and burn a person to death. if we develop our country and Nigerians learn to follow the law, Why will people go to Malaysia to school.

.

Nigerian general hospitals are also in a mess too!

The government should work on its healthcare, by providing free healthcare and also by legalizing abortion.

Equado:
you wed only once?get your facts right...most of this 'glamorous wedding' of yours how long does it last...my parents got married @ deeper life and that was 34yrs ago

On the average, Nigerians do not divorce.

And i know of a deeper life member who has two wives!

There are good and bad people everywhere.

tpia6:
the husband and wife resemble though.

I noticed.

are you the same Tpia from the old nairaland days.?

miredia:
Why aren't they all smiling Simple couple though. God bless their union

Marriage is not a joking matter. Why should they be laughing or smiling.

Adiwana:
I applied this method to a certain question & I failed it mean while here is the question

3^-5n/9^1-n × 27^n+1...thanks in advance

Could you rephrase this question.

.

With Factorization in Jamb, I highly suggest you work very closely with the given options.
Always expand the bracket to check if you are right.
There is a very high chance of mixing up signs, be extra careful

Iono if this is correct sha, but this what I got.

4A^2-12AB-C^2+9B^2

Rearrange
4A^2-12AB+9B^2-C^2
4A^2-6AB-6AB+9B^2-C^2
(4A^2-6AB)-(6AB+9B^2)-C^2
4A(A-3/2B)-6B(A-3/2B)-C^2
(4A-6B) (A-3/2B)-C^2

WORKING ON THE FIRST

I got a slightly different answer when working this

from your second step

(4a^2-6ab)-(6ab - 9b^2) - c^2

factorizing gives 2a(2a-3b)-3b(2a-3b)-c^2

this would be equal to (2a-3b)^2 -c^2

difference of two square a^2-b^2=(a-b)(a+b)

so in our situation 2a-3b is our a
And c is our b

difference of two squares (2a-3b-c) (2a-3b+c)- completely factorized


CHECK: opening bracket

4a^2-6ab+2ac-6ab+9b^2-3bc-2ac+3bc-c^2

4a^2-6ab-6ab+2ac-2ac+9b^2-3bc+3bc-c^2

after cancelling out 2ac and 3bc, we are left with

4a^2-12ab+9b^2-c^2

I'll do the first, since barack did the second.

Firstly separate y^3+xy^3-4y-4xy

Factorize y^3(1+x) -4y(1+x)

adding (y^3-4y) (1+x)

further factorization y(y^2-4)(1+x)

y^2-4= (y+2)(y-2)

overall y(y+2)(y-2)(1+x)

Same Example i did last time.

Y^3-4XY+XY^3-4Y
Another way is take out y
y(y^2-4x+xy^2-4)

rearranging the brackets
y(y^2+xy^2-4-4x)
factorizing inside brackets
y( y^2 (1+x)) - 4(1+x) )
y(y^2-4)(1+x)
same as before
y(y+2)(y-2)(1+x)

bolaji3071:
pls help me wit dis.

Factorize completely Y^3-4XY+XY^3-4Y
&
Factorize 4a^2-12ab-c^2+9b2

tanx

Respect is Reciprocal

he didnt respect the students when ASUU went on strike for months and him and his useless minister wike didnt do anytin or give a dam dt students were wasting valuable time at home

He didnt respect students when corpers nd applicants died while applying for immigration test uptill today the dg of immigration nd minister in charge has not been punished bt souls were not lost

one more thing ur mentality reminds me of a slave that is being tortured bt looks and smile and doesnt resist while his mates resists he smiles nd accepts evry sheet thrown at him

we r nt slaves here ..esp in our fatherland

and if u dnt know leadership is abt serving the people nt the people serving the leaders

Jonathan doesnt deserve any form of respect

he is a total failure

Good point!

STFU.... Even if he is the president of the world, what make him more human that you and I, aside mere ranks and law made by men like you and I?

In my book, all men are equal. If you like get Phd, I will treat you same way I will treat the begger off the street.

So are you saying that we should throw stones / water at people we dont like??
This is just a matter of respect.
We are always shouting About African values. Respect is one of them.
Let us treat each ther kindly. Thats all

If this report is true, then theses students are disrespectful.

Even if you dont like him, he is the president of Nigeria and should be treated with upmost respect.

goofyone:
That's that for number bases. I hope you guys enjoyed it. Any questions? Feel free to ask.

I'll treat an example from algebra, which is supposed to be the next module. The intent is to make one of the methods clear.
But just to note: you may not be able to apply this method to every question. The deal is to make you aware of these methods so that you could use a few of them in your exams. Just be cautious as you work. After this example in factorization, I'll see if I can treat a few questions under the remainder topics in SECTION I as outlined by dejt4u. I bet you, there are lot more tricks you'd learn in this section.



So, let me treat this question:

Factorize completely 4abx - 2axy -12b2x + 6bxy

A. 2x(a - 3b)(2b - y)
B. 2x(3b - a)(2b - y)
C. 2x(a - 3b)(y - 2b)
D. 2x(2b - a)(3b - y)

In order to solve this, you might want to start factorizing and trying to look for what's common and all that. Another wise method to use would be to use our method of substitution. Substitute a = 1, b = 1, and x =1

That'll give you

Factorize completely 4 -2 - 12 + 6 = -4

A. 2(1-3)(2-1) = -4
B. 2(3-1)(2-1) = 4
C. 2(1-3)(1-2) = 4
D. 2(2-1)(3-1)=4

You can immediately see that A is the answer.

Except you are fast enough to know how to quickly factorize, you may just want to adopt this method. In fact, something tells me it's not a coincidence only option A has a -4

For the factorization method, another method is to multiply and open the brackets individually. It may take some time but its also efficient. Option A is the right answer.

Solving this my way would be 4abx - 2axy -12b2x + 6bxy

separating equations (4abx-2axy)-(12b^2x-6bxy)
The Minus sign in front of the second bracket changes the signs of 12b^2x and 6bxy.

factorizing 2ax(2b-y)-6bx(2b-y)
Factorizing is identifying the common factors. 2ax is common to the first bracket and 6bx is common to the second

together (2ax-6bx) (2b-y)
Since (2b-y) is common, we take one of it ad multiply it 2ax-6bx

Further factorization 2x is common to both 2ax and -6bx.
so factorizing by 2x, we have:

2x(a-3b)(2b-y)
Compact form
4abx - 2axy -12b2x + 6bxy
(4abx-2axy)-(12b^2x-6bxy)
2ax(2b-y)-6bx(2b-y)
(2ax-6bx)(2b-y)
2x(a-3b)(2b-y)

adozie:
Nigerian government clearly doesn't know what to do with money. What is this trash? How will this affect the common man? How is this sustainable
We have gas right?...being flared and wasted every day.
Why can't government invest in efficient use of gas in Nigeria.
I bet if they set up a national competition for engineering students with just N1 million prize money to come up with a more efficient way to use gas in Nigeria for cooking, am sure you will be surprised by the outcome.
Despite the dwindling crude oil income, this government is still wasting money on stupidity. Who is advising these people?
Oh well, it's just another way to steal money. Shame on all of us the citizens of this country to watch these looters destroy our future

Oga , you are Funny oh.
Where are the Refineries that are Producing the Gas to Flare

This country has too many problems.
I don't mind if they give us gas cookers each, Let us chop small from the national cake too.

If you approve of this type of Punishment, its Alright.

But Don't come to Nairaland to Cry and Shout or Complain that army officers Slapped you, or flogged you and made you kneel down.

I don't know how anyone can approve of this injustice.

I can teach Chemistry and Maths...

How can I be a tutor. ??

When other people in the world Read this News, the headline used will be NIGERIAN man..

Why don't we just come together and condemn this Action as a country and forget about tribalism
