Homework Help: Algebra II

Posted by Jonathan on Wednesday, August 8, 2007 at 7:34pm.

Solve x^2>_2x+24


x^2-2x-24>=0
(x-6)(x+4)>=0

So as long as x>6, it works. But what about two negatives?
Try x=-5..checks...check me on that.

So it looks as if -inf<x<=-4 works, and
6<=x<inf works.

check that.
