Answer 2

a) 2x - 3y^2 * (3x - 2y - 4)

First, we'll distribute the -3y^2 to the terms inside the parentheses:

= 2x * 3x - 2x * 2y - 2x * 4 - 3y^2 * 3x + 3y^2 * 2y + 3y^2 * 4

Simplifying each term:

= 6x^2 - 4xy - 8x - 9xy^2 + 6y^3 + 12y^2

Finally, we can rearrange the terms:

= 6x^2 - 9xy^2 - 4xy + 12y^2 + 6y^3 - 8x

So the simplified expression is 6x^2 - 9xy^2 - 4xy + 12y^2 + 6y^3 - 8x.
