Homework Help: Pre Calculus

Posted by Anonymous on Wednesday, September 18, 2013 at 11:15am.

So I only have 3 homework questions left and I can't seem to figure out how to solve. I've tried solving them, but I keep getting them wrong. Any help?

Factor the polynomials:
a) 3x^2 +19x - 40

b) x^4 - 25x^2

Simplify the expression completely:

(1/(x-h)^3 - 1/x^3)/8h
