STEP 2:

STEP 3 :

Pulling out like terms

3.1 Pull out like factors :

3x2 + 9x = 3x • (x + 3)

Equation at the end of step 3 :

15x • (x + 3) - 14

STEP 4 :

Trying to factor by splitting the middle term

4.1 Factoring 15x2+45x-14

The first term is, 15x2 its coefficient is 15 .

The middle term is, +45x its coefficient is 45 .

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

Answer 2

Express 5 onto the terms in the parenthesis, then you will get the following, 15x^2 + 45x - 14
