Question

What is the sum of the polynomials?

(–x2 + 9) + (–3x2 – 11x + 4)

Answer 1

-4x^2-11x+13. The symbol ^ means for the 2 is to the power

Answer 2

`-4x^2-11x+13`

Explanation:

We have to find the sum of the polynomials
`(-x^2+9)+(-3x^2-11x+4)`

Distribute the plus sign over the parenthesis

`-x^2+9-3x^2-11x+4`

Now, group the like terms

`-x^2-3x^2-11x+4+9`

Now, combine the like terms

`-4x^2-11x+13`

Therefore, the sum of the polynomials is
`-4x^2-11x+13`
