Question

1. combine like terms. 2 + 2 + 7y^{3}-6y^{3}+1 - 3y^{3}+y

Explanation:

Step1: Combine constant - terms

$2 + 2+1=5$

Step2: Combine $y^{3}$ terms

$7y^{3}-6y^{3}-3y^{3}=(7 - 6-3)y^{3}=-2y^{3}$

Step3: Keep the $y$ term

The $y$ term remains as $y$.

Step4: Combine all results

$5-2y^{3}+y$

Answer:

$-2y^{3}+y + 5$
