Answer 1

$- {x}^{2} + 9 - 3 {x}^{2} - 11x + 4 \\ = - 4 {x}^{2} - 11x + 13$

2nd answer

Answer 2

Answer:

Option B. -4x² - 11x + 13

Step-by-step explanation:

Given polynomials are ( -x² + 9 ) and ( -3x² - 11x + 4 )

We have to add them.

( -x² + 9 ) + -3x² - 11x + 4 )

-x² + 9 - 3x² - 11x + 4

Now we will collect similar terms

( -x² - 3x² ) - 11x + ( 9 + 4 )

-4x² - 11x + 13

Therefore, option B is the answer.
