1. ## A basic factoring question

2x -7/x^2 +5 -24

The book gives the answer of -8 and 3. I understand (x-3)(x+8).

But when I did the problem I wrote it as (x-8)(x+3). Therefore the answer is wrong?

Is it the same thing? If not then why?

Thank you very much in advance.

(x-3)(x+8) is the same denominator which is factored!

3. there in $\frac {2x-7}{x^2+5-24}$ is missing 5x i think ...

$(x-3)(x+8) = x^2+5x-24$

but

$(x+3)(x-8) = x^2-5x-24$

that's why it's not the same... if that's what you are asking
