 * When factoring trinomials that are equal to 1, you can use **Reverse FOIL and c>0** **and Reverse FOIL and c<0. **
 * **Reverse FOIL and c>0**
 * To reverse FOIL, find two numbers whose product is c and sum is b. If c is positive, the signs in the two binomials __**have to stay the same.**__
 * Example:x 2 +10x+24
 * Find Factors of 24: 6*4, 2*12, 24*1, 8*3
 * Factor: **(x+6)(x+4)**
 * ** Reverse FOIL and c<0 **
 * To reverse FOIL here, find two numbers whose product is c and sum is b. If the c is negative, the binomial signs __**have to be different.**__
 * Example: x 2 +x-6
 * Find factors of -6: -3*2, 3*-2, -6*1, 6*-1
 * Factor: **(x+3)(x-2)**
