Question

simplify. (5y^2 - 2y + 7)+(-6y^2 + 4y + 3)

Explanation:

Step1: Remove parentheses

$5y^{2}-2y + 7-6y^{2}+4y + 3$

Step2: Combine like - terms for $y^{2}$ terms

$(5y^{2}-6y^{2})= - y^{2}$

Step3: Combine like - terms for $y$ terms

$(-2y + 4y)=2y$

Step4: Combine constant terms

$(7 + 3)=10$

Step5: Write the simplified expression

$-y^{2}+2y + 10$

Answer:

$-y^{2}+2y + 10$
