Answer:
-3y^2 - 6y - 17
Step-by-step explanation:
-3(y + 2)^2 - 5 + 6y =
Expand the square of the binomial.
= -3(y + 2)(y + 2) - 5 + 6y
Use FOIL to multiply the binomials.
= -3(y^2 + 2y + 2y + 4) - 5 + 6y
Combine like terms inside the parentheses.
= -3(y^2 + 4y + 4) - 5 + 6y
Distribute the -3.
= -3y^2 - 12y - 12 - 5 + 6y
Combine like terms.
= -3y^2 - 6y - 17
