Math(solving a quadratic by factoring)

posted by on .

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.
