To factor the polynomial 8x²y + 14xy + 12x + 21, let's follow the factor by grouping method:

Step 1: Group the terms:
(8x²y + 14xy) + (12x + 21)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out 2xy: 2xy(4x + 7).
In the second group, we can factor out 3: 3(4x + 7).
