    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.

    Is it an equation?! Please clear your meaning...

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

    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
