We can factor the polynomial 5x³ + 10x² + 6x + 12 using the factor by grouping method:

Step 1: Group the terms: (5x³ + 10x²) + (6x + 12)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out 5x²: 5x²(x + 2).
In the second group, we can factor out 6: 6(x + 2).
