I want to implore Nigerians not to follow aba made fake product but the original tested n trusted man

Imagine a man that made doctors go on strike for 13 months telling u he will do well in health sector?
Isn’t it laughable

Imagine a man who refuse to pay lecturers for good 6 months telling u he values education n to add insult on injury he increased ANSU tuition fee by 200%
Isn’t it laughable?

Imagine a man who fails to conduct local government election for good 7 years telling u he will deliver dividends of democracy to u, y didn’t he to that when he was governor?

Imagine a man who can’t manage a majority Christian state n even had to start divide n rule between catholic n others Christian’s telling u he will unite u
No b craze b dat?

The same man who killed youths extrajudicially n dumped their bodies inside awkuzu river telling u he will protect the youth, Nigerians ronu

He’s telling u he will move us from consumption to production but he’s the greatest importer of what his brothers are manufacturing locally

Same man that claim he needs to b stingy by denying people dividends of democracy is stashing money into teenage daughter account n even have numerous offshore accounts

The same man who said he wants to change d old order still romancing obj, ibb, enenche of endsars n the latest the billionaire grass cutter

In Sowore voice…. A thief can’t fix your window

This is what Owobokiri has to say about him then, ask him what has changed today?

Please you guys should add support MathJax to this forum so that we can benefit from seeing better formated mathematical equations.

I think that will boost the activity of helping people with calculations in the education section.

Thank you.

Idi0t!! "Quadratic formula" and "completing the square method" are one and the same method. Quadratic formula can be derived from completing the square.

I know the questions are no big deal but I decided to allow ChatGPT solve them. See the output below:

Quadratic Formula Solution

Solve Solve X^2 + 2X - 8 = 0
Using the quadratic formula

The quadratic formula for solving the equation ax^2 + bx + c = 0 is: x = (-b ± √(b^2 - 4ac)) / 2a

So in this case, we have:
x^2 + 2x - 8 = 0
x = (-2 ± √(2^2 - 4(1)(-cool)) / 2(1)
x = (-2 ± √(4 + 32)) / 2
x = (-2 ± √(36)) / 2
x = (-2 ± 6) / 2
x = (-2 + 6) / 2 or x = (-2 - 6) / 2
x = 2 or x = -4

Therefore, the solutions of the equation are x = 2 and x = -4


Solve X^2 - 3X - 18 = 0 using completing the Square

To solve x^2 - 3x - 18 = 0 using completing the square method, we can follow these steps:

Rewrite the equation in the form of x^2 - 3x = 18 by adding 18 to both sides.
Add (3/2)^2 to both sides of the equation to get a perfect square trinomial on one side of the equation: (x-3/2)^2 = (3/2)^2 + 18.
Take the square root of both sides of the equation: x-3/2 = ± √((3/2)^2 + 18)
Add 3/2 to both sides of the equation: x = 3/2 ± √((3/2)^2 + 18)
Solve for x by simplifying the square root: x = 3/2 ± √(9/4 + 18) = 3/2 ± √(81/4) = 3/2 ± 3/2 = 6 or x = -3
Therefore, the solutions of the equation are x = 6 and x = -3.

The solutions to the quadratic equation X^2 + 2x - 8 = 0 are x = -4 and x = 2.
You can use Quadratic Formula : x = (-b ± √(b^2-4ac)) / 2a
In this case a=1, b=2 and c=-8.
x = (-2 ± √(2^2-41(-cool)) / 2*1
x = (-2 ± √(4+32)) / 2
x = (-2 ± √(36)) / 2
x = (-2 ± 6) / 2
x = (-4) / 2 or x = 2/2
x = -2 or x = 1
