Trinomial+Where+a+=1


 * // what is a trinomial? A x 2 + //** //** B **// **// x + //** **// C //**

**__Step 1__:** Make two sets of parenthesis and put as follows (x )(x ), because the first step of **FOIL**ing is "**F**irst" and you know that 1x times 1x is the only way to get x 2. __**Step 2:**__ Find the signs(+ or -) and numbers. To find the numbers, ask yourself "What two numbers have a product of C but a sum of B?". __**Step 3:**__ FOIL out the factors and check your answer. It should be the same trinomial that you started with.

example 1: x 2 + x - 6 (x )(x ) (x+ )(x- ) (x+3)(x-2)

example 2: x 2 - 5x - 24 (x )(x ) (x+ )(x- ) (x+3)(x-8)
