Answer 2

To simplify the expression $(3a - 1)(2a + 3) - 6(a + 1)^2$, you can follow these steps:

Step 1: Expand the two terms within the first set of parentheses.

$(3a - 1)(2a + 3) = 3a * 2a + 3a * 3 - 1 * 2a - 1 * 3$

Step 2: Simplify the expression within the first set of parentheses.

$6a^2 + 9a - 2a - 3$

Step 3: Combine like terms.

$6a^2 + (9a - 2a) - 3 = 6a^2 + 7a - 3$

Now, you have the simplified expression $(3a - 1)(2a + 3) - 6(a + 1)^2 = 6a^2 + 7a - 3 - 6(a + 1)^2$.
