Trinomial+Where+A+≠+1

__**Trinomial Where A ≠ 1**__
 * When factoring trinomials where a ≠ 1, two main methods are used: **Guess and Check** **and Factoring by Grouping .**
 * __**Guess and Check.** __
 * When using this method, you simply try every solution you can until it factors out.
 * Ex. 2x 2 +9x-5
 * Find the Factors of -5 = 1,-5 and -1,5
 * Guess and Check
 * (2x-1)(x+5) or (2x+1)(x-5)
 * the first one solves to be 2x 2 + 9x-5 (the right answer) and the second one solves to be 2x 2 -9x-5 (the wrong answer)
 * __** Factoring by Grouping. **__
 * When using this method, you separate the two factorial statements by undergoing a series of steps
 * Factor: ax 2 +bx+c
 * 1) First, multiply a and c=ac
 * 2) Second, find two factors of ac whose sum is b.
 * 3) Third, split the middle term by using the two factors.
 * 4) Then, group the first two and last two terms.
 * 5) Last, factor out the GCF from each group and rewrite.
 * Example: 6x 2 -13x-5
 * 1) 6*-5=-30
 * 2) -15+2=-13 and -15*2=-30
 * 3) 6x2-15x+2x-5
 * 4) (6x2-15x)+(2x-5)
 * 5) 3x(2x-5)+(2x-5)
 * 6) **(3x+1)(2x-5)**
