Question

What is the answer to this problem.

Answer 1

`2a^2 + 3x - 2a`

Explanation:

`(6a^2 + 3x) - (4a^2 + 2a) =`

The first set of parentheses is unnecessary and can be removed.

`= 6a^2 + 3x - (4a^2 + 2a)`

To remove the second set of parentheses, you must distribute the negative sign to its left as if it were a -1 multiplying the quantity inside the parentheses.

`= 6a^2 + 3x - 1(4a^2 + 2a)`

`= 6a^2 + 3x - 4a^2 - 2a`

Now combine like terms. Like terms are terms with the same variable part.

`= 2a^2 + 3x - 2a`
