Answer:
-8x^2 + 11x + 9
Explanation:
To solve the expression (−8x^2+5x+3)+(6x+6), you need to combine like terms. First, distribute the addition through the parentheses:
(−8x^2 + 5x + 3)+ 6x + 6
Combine like terms:
-8x^2 + (5x + 6x) + (3 + 6)
Combine the x terms and the constant terms separately:
-8x^2 + 11x + 9
