[tex] - {x}^{2} + 9 - 3 {x}^{2} - 11x + 4 \\ = - 4 {x}^{2} - 11x + 13[/tex]
2nd answer
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.
