Flytefalls: Well finally! Nice to meet u, I hate being contrived! 190 is funny, but you're nuts . You've not shown us your full potential but I have faith, I remember your wacky posts I've commented in before. Mad man ah rule tings hya soh! But 190 is my nl heart throb 4 life. The reason why I signed up

Yeah I do stats analysis... I enjoy this over pure maths. I hate maths!!!! *hulk exhale*

You also enjoy winning, dont you? undecided

Nice lips...

Odunnu: I beg you again, use the complaints thread next time you want the attention of any of the MODs. If you just vent off here, very likely none of us will see and take action.
You are lucky now though

Thank you.

Abiola4eva: gurus pls hlp solve ds quesion,wat will b d value of a,b nd c, in ds binomial expansion (a+bx)^c,if d coefficient of 2nd,3rd nd 4th term are -12,60 nd -160 respectively.

I am doing this a second time...

Based on binomial theorem each term of (a+bx)^c is n!/(n-k)!k!*a^(c-k)*(bx)^k
Where k=0, 1, 2, 3, 4,..., c and "*" stands for multiplied by

2nd term; n!/(n-1)!1!*a^(c-1)*(bx)^1
3rd term; n!/(n-2)!2!*a^(c-2)*(bx)^2
4th term; n!/(n-3)!3!*a^(c-3)*(bx)^3

Sifting out x coefficients;

n!/(n-1)!1!*a^(c-1)*b^1=-12..........eq1
n!/(n-2)!2!*a^(c-2)*b^2=60.........eq2
n!/(n-3)!3!*a^(c-3)*b^3=-160.........eq3

Combining equations 1 and 2 noting dat -5*-12=60 where -12=n!/(n-1)!1!*a^(c-1)*b^1

n!/(n-2)!2!*a^(c-2)*b^2=-5*n!/(n-1)!1!*a^(c-1)*b^1
>>(n-1)!/(n-2)!*b=-5*a
Note (n-1)!=(n-1)(n-2)!
>>(n-1)*b=-5*a.........eq4

Combining equations 2 and 3 noting dat -8/3*60=-160

n!/(n-3)!3!*a^(c-3)*b^3=-(8/3)*n!/(n-2)!2!*a^(c-2)*b^2
>>(n-2)!2!/(n-3)!3!*b=-(8/3)*a
>>(n-2)!/3*b=-(8/3)*a..........eq5

Dividing equation 5 with 4 to eliminate a and b.

>>-5*(n-2)=-8*(n-1)
>>5c-10=4c-4
>>c=6

Miss Odunnu, my post was hiden for no apparent reason. Its painful, I took time to solve a math problem only for it to be wiped off by Pyguru. I don't understand why.

You made me sweat some...
Based on the binomial theorem each term of (a+bx)^c can be expressed as;

c!/[(c-k)!k!]*a^(c-k)*(bx)^k

Where k= 0, 1, 2, ..., c
I am going to use "*" as multiplied by.
Now,

2nd term : c!/[(c-1)!1!]*a^(c-1)*(bx)^1

3rd term : c!/[(c-2)!2!]*a^(c-2)*(bx)^2

4th term : c!/[(c-3)!3!]*a^(c-3)*(bx)^3

Sifting out the coefficients

c!/[(c-1)!1!]*a^(c-1)*(b)^1=-12......eq1
c!/[(c-2)!2!]*a^(c-2)*(b)^2=60......eq2
c!/[(c-3)!3!]*a^(c-3)*(b)^3=-160......eq3

Now combining equation 1 and 2

c!/[(c-2)!2!]*a^(c-2)*(b)^2=-5[c!/[(c-1)!1!]*a^(c-1)*(b)^1]
***remember -5x-12=60 where -12 is c!/[(c-1)!1!]*a^(c-1)*(b)^1***

Now combining equation 2 and 3

c!/[(c-3)!3!]*a^(c-3)*(b)^3=-(8/3)[c!/[(c-2)!2!]*a^(c-2)*(b)^2]
***-(8/3)x60=-160***

Simplifying;

(c-1)!/(c-2)!2!*b=-5*a
>>(c-1)(c-2)!/(c-2)!2!*b=-5*a ***(c-1)!=(c-1)(c-2)!***
>>(c-1)/2*b=-5*a

Next,
(c-2)!2!/(c-3)!3!*b=-(8/3)*a
>>(c-2)(c-3)!2!/(c-3)!3!*b=-(8/3)*a
>>(c-2)/3*b=-(8/3)*a

we devide this two results to eliminate a and b (akara and bread)

[(c-1)/2*b=-5*a]/[(c-2)/3*b=-(8/3)*a]
>>5c-10=4c-4
>>c=6 yo yo!!!! Uh uh

Now

2nd term : 6!/5!*a^5*b=-12
3rd term : 6!/4!2!*a^4*b^2=60
4th term : 6!/3!3!*a^3*b^3=-160

4th term looks promising
6!/3!3!*a^3*b^3=-160
>>a^3*b^3=-160/(6!/3!3!)
>>a^3*b^3=-8
>>(ab)^3=-8
>>ab=-2

feed it back b=-2/a,

6!/5!*a^5*(-2/a)=-12
>>6*5!/5!*a^4=6
>>a=1
>>b=-2

so... a=1, b=-2, c=6
