Question

How do you add `(4x^2-x-7) + (2x^3+6x^2-11)`?

Answer 1

Combine like terms to get the answer, `2x^3+10x^2-x-18`.

Explanation:

Let's get rid of the parentheses, since there are no coefficients or negative signs outside of the parentheses:

`4x^2-x-7+2x^3+6x^2-11`

Let's reorganize the equation to combine like terms and solve:

`2x^3+4x^2+6x^2-x-7-11`
`2x^3+10x^2-x-18`
