Question

Find the sum and express it in simplest form. (-5y^3-7y-7)+(7y^3+8y)

Answer 1

Since the operation between the sets of parentheses is addition, we can just remove the parentheses all together and add like terms together to find the simplest form.

-5y^3-7y-7+7y^3+8y
(-5+7)y^3+(-7+8)y-7
2y^3+y-7
