Pulling out like terms

4.1 Pull out like factors :

2x3 - 10x2 - 28x = 2x • (x2 - 5x - 14)

Trying to factor by splitting the middle term

4.2 Factoring x2 - 5x - 14

The first term is, x2 its coefficient is 1 .

The middle term is, -5x its coefficient is -5 .

The last term, "the constant", is -14

Step-1 : Multiply the coefficient of the first term by the constant 1 • -14 = -14

Step-2 : Find two factors of -14 whose sum equals the coefficient of the middle term, which is -5 .

-14 + 1 = -13

-7 + 2 = -5 That's it
