Answer:

x⋅(2x+1)⋅(2x+3)⋅(3x−2)

Step-by-step explanation:

Equation at the end of step 1

(((12•(x4))+(16•(x3)))-7x2)-6x

STEP

Equation at the end of step

(((12 • (x4)) + 24x3) - 7x2) - 6x

STEP

Equation at the end of step

(((22•3x4) + 24x3) - 7x2) - 6x

STEP

Pulling out like terms

5.1 Pull out like factors :

12x4 + 16x3 - 7x2 - 6x =

x • (12x3 + 16x2 - 7x - 6)

Checking for a perfect cube :

5.2 12x3 + 16x2 - 7x - 6 is not a perfect cube
