(-3x^2 - 5x + 1) + (8x^2 - 2x - 9)
1st remove the parenthesis
-3x^2 - 5x + 1 + 8x^2 - 2x - 9
then combine like terms
5x^2 - 7x - 8 is the final answer
hope it helps you!!!!!!!!!!
Well actually when i did this equation i got y=3 so you might want to recheck your answer and take another look at the steps you took.
Hopefully this helped you ^0^
