Homework Help: math

Posted by kristie on Tuesday, July 25, 2006 at 6:39pm.

please help me simplify

(x^3+8)/(x^4-16).

thanks.


The denominator is cleary the differerence of two squares (X^2-4)(x^2+4). That can again be factored to (x+2)(x-2)(x^2+4).

The numerator can be factored using the trinomial simplification..

so (x^2-2x+4)/((x-2)(x^2+4)) is as far as I can go?
