Homework Help: Math(solving a quadratic by factoring)

Posted by Nick on Monday, March 3, 2008 at 3:00pm.

Ok I get most of the problems except for these last two.

x^2-16=0

and

x^2=36

I seem to have trouble with the simplest of problems and none at all with the hard ones.

These follow the pattern of
(x+number)(x-number) when the number is a perfect square. So
(x+4)(x-4) is the first.
Rearrange the second one to
X^2 - 36 = 0 and factor the same way.
