Ok so we fisr notice that theres a - sign in between the 2 parehteses therefore we need to distrubite theres no varible there so we assume its 1 \(\huge\rm\color{red}{-}(4y^2+6y+9)\) We distribute and bascially the signs slip we end up with \(\huge\rm\color{red}{-4y^2-6y-9}\)

From there we combine like terms \[\huge~\rm~-3y^2 - 7y - 9−4y^2−6y−9 \]
