We can factor the polynomial 7x³ + 14x² + 8x + 16 using the factor by grouping method:

Step 1: Group the terms: (7x³ + 14x²) + (8x + 16)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out 7x²: 7x²(x + 2).
In the second group, we can factor out 8: 8(x + 2).
