Guest, here are some easy identities for simplifying quadratics.

First, if a quadratic is in the form **a^2 - b^2**, then the form of the factored equation would be **(a+b)(a-****b)**. This is called the difference of squares.

Second, if in the normal quadratic form of **a****x ^2 + bx + c**, then one must find a number that adds up to b, and multiplies to c. If a is a coefficient of a > 1, then one must find a number that adds to b and multiplies to ac.

Hope this helps!
