For this case we have the following polynomials:

\(-x ^ 2 + 9

-3x ^ 2 - 11x + 4
\)

Adding the polynomials we have:


\((-x ^ 2 + 9) + (-3x ^ 2 - 11x + 4)
\)

Rewriting we have:


\(x ^ 2 (-1-3) - 11x + (9 + 4)
\)

Therefore, the result of the sum is:

\(-4x ^ 2 - 11x + 13
\)

Answer:

the sum of the polynomials is:

\(-4x ^ 2 - 11x + 13
\)
