:
Pulling out like terms
3.1 Pull out like factors :
2x2 - 2x - 112 = 2 • (x2 - x - 56)
Trying to factor by splitting the middle term
3.2 Factoring x2 - x - 56
The first term is, x2 its coefficient is 1 .
The middle term is, -x its coefficient is -1 .
The last term, "the constant", is -56
Step-1 : Multiply the coefficient of the first term by the constant 1 • -56 = -56
Step-2 : Find two factors of -56 whose sum equals the coefficient of the middle term, which is -1 .
