Answer 2

It seems like you've provided an expression with several terms. To simplify the expression, let's combine like terms and perform the necessary calculations.

The given expression is: Ac + 2abc - 7a^2 + 3ac - 3abc

First, let's group the like terms: Ac + 3ac = 4ac 2abc - 3abc = -abc

Now the expression becomes: 4ac - abc - 7a^2

That's the simplified form of the given expression.
