To factor the polynomial 2a² + 3ab + 2a + 3b + 1, let's follow the factor by grouping method:

Step 1: Group the terms: (2a² + 3ab) + (2a + 3b) + 1

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

Now, we have: a(2a + 3b) + (
