Re: Factoring Polynomials

I am leaning towards E. So far it can be done by grouping and perfect squares method.

Re: Factoring Polynomials

Hi;

That is not correct. Did you try to factor that by the  difference of two squares. Can you see two squares there? No, you can not. The answer is F

Re: Factoring Polynomials

i think that if a polynomial can be factored by any other method than it can also be done by grouping.

Re: Factoring Polynomials

What did you get?

You should get ( x - 3 ) ( x + 5 )

x^2+2x-15
15*x=15x= 5 , -3
(x^2+5x)-(3x-15)
x(x+5)-3(x-5)
(x-3) (X+5)

Correct, please do not change x to X, those are different variables and mean different things.
