    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 \[\huge~\rm~-3y^2 - 7y - 9−4y^2−6y−9 \]

    \(\huge\rm\color{red}{-3y^2-4y^2=?}\) \(\huge\rm\color{purple}{-7y-6y=?}\) \(\huge\rm\color{teal}{-9-9=?}\)

    @oleg3321 its called learning and explaining. Here on OpenStudy we do not give direct answers.
