    Heres my work : 4y^2 (- 6y2) (-12y^2 - 3y + 6) (-9y^2 + -6y) (-15) (4y^2 - 6y^2 - 12y^2 - 9y^2) (-3+-6y) (6 - (-15)

    (-3 + 6y) is supposedd to be (-3y + -6y) I collected the like terms, but i think im doing something wrong. the answer is supposed to be y^2 - 9y +21

    what i did was subtract 4y2 - 6y2 and it gave me 2 and then 12y2 - 9y2 and it gave me 3 and i subtracted that and it gave me -y2 but it doesnt sound right
