Equation at the end of step 1

(2x2 + 6x) - 36 = 0

STEP

3

:

Pulling out like terms

3.1 Pull out like factors :

2x2 + 6x - 36 = 2 • (x2 + 3x - 18)

Trying to factor by splitting the middle term

3.2 Factoring x2 + 3x - 18

The first term is, x2 its coefficient is 1 .

The middle term is, +3x its coefficient is 3 .

The last term, "the constant", is -18

Step-1 : Multiply the coefficient of the first term by the constant 1 • -18 = -18

Step-2 : Find two factors of -18 whose sum equals the coefficient of the middle term, which is 3 .

-18 + 1 = -17

-9 + 2 = -7

-6 + 3 = -3

-3 + 6 = 3 That's it
