The like terms are: 7y^2 and 8y^2 -3y and -8y. Add them. 7y^2 + 8y^2 = 15y^2 -3x + (-8y) = -3y - 8y = -11y So the answer would be 15y^2 - 11y

Answer:

15y² - 11y

Step-by-step explanation:

We have to combine like terms  in the given expression :

(7y² - 3y) + (8y² - 8y)

Here second degree term y² and y are the like terms.

So by combining these terms we can solve this.

(7y² + 8y²) - (3y + 8y)

= 15y² - 11y

Therefore, answer is 15y² - 11y
