Can you figure it out?c For the prize?

Recommended Posts

Now that you figured this part out the next part is a math problem solve it and you get 10 points! Give me the answer with this color code(hex) #202020 so no one else can understand..

Here is the problem (x-4)(x+9)

=(x + -4)(x + 9) = 0

= (-4 + x)(x + 9) = 0

= (-4 + x)(9 + x) = 0

= (-4 + x) * (9 + x) (-4(9 + x) + x(9 + x)) = 0 ((9 * -4 + x * -4) + x(9 + x)) = 0 ((-36 + -4x) + x(9 + x)) = 0 (-36 + -4x + (9 * x + x * x)) = 0 (-36 + -4x + (9x + x2)) = 0

= -4x + 9x = 5x (-36 + 5x + x2) = 0

=-36 + 5x + x2 = 0

=(-9 + -1x)(4 + -1x) = 0.

I'm no good in math BTW.

7x-36 

Its been a while but I'm pretty sure that this is correct.

How do you even solve that? It is an expression there is no answer to it. If you had set it equal to something or y then it would be possible. But assuming you wanted it set equal to 0 the answers are 4,-9

I'm sorry I should have clarified the solution a problem like this has two answers the ones are: x^2(this is x squared)

X^2+5x-36, x=4 x=-9

I will make that is more clear: Find the x and y intercept(s) with the equation y=x^2+17+72
