Question

What is the sum of the polynomials?

(–x2 + 9) + (–3x2 – 11x + 4)

–4x2 – 2x + 4
–4x2 – 11x + 13
2x2 + 20x + 4
2x2 + 11x + 5

Answer 1

-4x^2 - 11x + 13. :)

Answer 2

For this case we have the following polynomials:

`image`

Adding the polynomials we have:

`image`

Rewriting we have:

`image`

Therefore, the result of the sum is:

`image`

Answer:

the sum of the polynomials is:

`image`
