# Math Help - Do i factor first or do i simplify first?

1. ## Do i factor first or do i simplify first?

$\frac{x^2+6x+5}{x^2-25}$

So do i simplify or factor first?

As I can't see a way to simplify this (unless you want to do a division problem) then I would factor first.

3. Ok, so i would get $(x+5)(x+1)over(x+5)(x-5)$

Do i just leave it like that?

No, now you have the problem in a form where you have a common x + 5 in the numerator and denominator. NOW divide. But remember that you can't divide by 0, so at the end you must write the line $x \neq -5$.
