Math(solving a quadratic by factoring)
posted by Nick .
Ok I get most of the problems except for these last two.
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.
Woo! Thanks a lot DrBob.
