Question

(2x^3-x^2-17x+12) ÷(3+x) ​

Answer 1

Step-by-step explanation:

STEP1:Equation at the end of step 1

(((2 • (x3)) - 3x2) - 17x) - 12

STEP 2 :

Equation at the end of step2:

((2x3 - 3x2) - 17x) - 12

STEP3:Checking for a perfect cube

 3.1    2x3-3x2-17x-12  is not a perfect cube

Trying to factor by pulling out :

 3.2      Factoring:  2x3-3x2-17x-12 

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  -17x-12 

Group 2:  2x3-3x2 

Pull out from each group separately :

Group 1:   (17x+12) • (-1)

Group 2:   (2x-3) • (x2)
