Answer:
2 • (x² + 2) • (x + 3)
Step-by-step explanation:
Pull out like factors :
2x³ + 6x² + 4x + 12 =
2 • (x3 + 3x²+ 2x + 6)
:
x³ + 3x² + 2x + 6 is not a perfect cube
Trying to factor by pulling out :
Factoring: x³ + 3x² + 2x + 6
Group 1: 2x + 6
Group 2: x³ + 3x²
Group 1: (x + 3) • (2)
Group 2: (x + 3) • (x²)
-------------------
Add up the two groups :
(x + 3) • (x² + 2)
