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

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

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.
