To solve this correctly, you need to make sure to distribute the negative onto both terms in the second parentheses.
So fully expanded, the problem would be:
2y² + 8y -7 + 3y - 3 = ?
You can easily rearrange the terms, or just do it in your head!
It would become:
2y² + 8y +3y -7 -3
= 2y² + 11y -10
Make sure you keep the terms with different variables separate! I hope this is helpful!
