Question

Simplify fully 4a sqaured +8a +2 I-a squared +9a -3

Answer 1

The simplified expression is:
`3a^2 + 17a - 1`

Explanation:

We are given the following expression:

`4a^2 + 8a + 2 - a^2 + 9a - 3`

We can fully simplify the expression by combining the like terms. So

`4a^2 + 8a + 2 - a^2 + 9a - 3 = 4a^2 - a^2 + 8a + 9a + 2 - 3 = 3a^2 + 17a - 1`

The simplified expression is:
`3a^2 + 17a - 1`
