Question

Preform the indicated operations and simplify your answer for the expression:
1/(x^2 -7x -8)   -   x/(x^2 -12x-32)

callisto · Answer

First, factor the denominators.
(x^2 -7x -8) = x^2 -8x +x - 8 = x(x-8) + (x-8) = ...?
(x^2 -12x-32) = Eh?! Is there any typo for this one??

anonymous · Answer

nope!no typos! i was doing that, factoring the denominators, and then that happened 0.0

If there is something wrong in this, then maybe the answer is No Solution?

anonymous · Answer

that wasnt a multiple choice answer 0.0

callisto · Answer

If no typo...... (Sorry, I still can't believe it.... Are you sure it is -32 not +32?)

callisto · Answer

If there are no typos... then..
$$\frac{1}{(x^2 -7x -8)}   -   \frac{x}{(x^2 -12x-32)} $$$$=\frac{1(x^2 -12x-32)}{(x^2 -12x-32)(x^2 -7x -8)}   -   \frac{x(x^2 -7x -8)}{(x^2 -12x-32)(x^2 -7x -8)} $$$$=\frac{x^2 -12x-32-x(x^2 -7x -8)}{(x^2 -12x-32)(x^2 -7x -8)} $$And then, simplify it...
