Answer 2

Sure, I'd be happy to help you with this algebraic expression!

Let's simplify the expression step by step:

1. Combine like terms: 7a^2 + (-3a^2) + (-4a^2)

To combine the terms, you can simply add the coefficients of the like terms: (7 - 3 - 4) * a^2

2. Perform the arithmetic operation within the parentheses: (0) * a^2

3. Anything multiplied by 0 is equal to 0, so the final simplified expression is: 0

Therefore, the result of the expression 7a^2 + (-3a^2) + (-4a^2) is 0.
