6y^2-12y-4

Step-by-step explanation:

(8y^2-5y+7) - (2y^2+7y+11)

(8y^2-5y+7)-2y^2-7y-11

Combine like terms:

6y^2-12y-4

14y^3 - 8y^2 - 5y + 7

Step-by-step explanation:

Simplify and then combine like terms.

Original problem: 2y^2 + 7y + 11 - 8y^2 - 5y + 7

Simplified: 14y^3 + 11 - 8y^2 - 5y + 7

And then combined:  14y^3 + 11 - 8y^2 - 5y + 7

Combined continued: 14y^3 -8y^2 -5y +11 + 7

Final: 14y^3 - 8y^2 - 5y + 7

I already excluded anything that was written as "+ -(insert number)" because it would still end up to be "-" or a subtract/negative.

I hope this helps, and that I did it right.
