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

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:

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

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