To factor the polynomial 3x² + 5xy + 3x + 5y, let's follow the factor by grouping method:

Step 1: Group the terms: (3x² + 5xy) + (3x + 5y)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out x: x(3x + 5y).
In the second group, there is no common factor: (3x + 5y).

Now, we have: x(3x + 5y) + (3x + 5y...
