Answer by MathLover1(20849) (Show Source): You can put this solution on YOUR website!
what you are looking for is called and
so, you have to to expand "" into terms, such that one term will have a with and the other will have a with
for example:
you are going find numbers that are factors of (these are ) ) that to ()
these factors are and
so you would rewrite the equation as:
(doing so,you didn't really change anything, because , so the integrity of the expression is still there)
now you factor in parts. from the first part, take out , from the second, take out
so, you have:
. . . . (if you notice, both of the terms in the ()'s are the same, this will always happen if it doesn't, you have done something wrong
then you say:
...that's factored
if u multiply this out, you will get back to the original expression of
