Question

Find the sum and express it in simplest form. (3t2 + 6t + 1) + (-9t2 - 5t)

Answer 1

`-6t^2+t+1`

Explanation:

First off, this is an addition problem, so the parenthesis are unnecessary. Remove them and group the like terms next to each other, just for ease:

`3t^2-9t^2+6t-5t+1`

Combining like terms gives you

`-6t^2+t+1`
