Question

i need help finding the answer for 5(3x2 + 9x) – 14

Answer 1

Answer:

15x2 + 45x - 14

Step-by-step explanation:

Equation at the end of step 1

 (5 • (3x2 +  9x)) -  14

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
