add. simplify your answer. (-2y^2 - 8y + 6) + (3y^2 + 3y - 11)

Explanation:

Step1: Combine like - terms of $y^{2}$

$(-2y^{2}+3y^{2})=(-2 + 3)y^{2}=y^{2}$

Step2: Combine like - terms of $y$

$(-8y + 3y)=(-8 + 3)y=-5y$

Step3: Combine constant terms

$(6-11)=-5$

Step4: Write the simplified expression

$y^{2}-5y - 5$

Answer:

$y^{2}-5y - 5$
