Answer:
[tex]-4x^2-11x+13[/tex]
Step-by-step explanation:
We have to find the sum of the polynomials [tex](-x^2+9)+(-3x^2-11x+4)[/tex]
Distribute the plus sign over the parenthesis
[tex]-x^2+9-3x^2-11x+4[/tex]
Now, group the like terms
[tex]-x^2-3x^2-11x+4+9[/tex]
Now, combine the like terms
[tex]-4x^2-11x+13[/tex]
Therefore, the sum of the polynomials is [tex]-4x^2-11x+13[/tex]
