Xavier Greene · Answer 1

(y+3) (y^2-3y + 9) = (y+3) (y^2 + - 3y + 9) = (y) (y^2) + (y) (-3y) + (y) (9) + (3) (y^2) + (3) (-3y) + (3) (9) = y^3 - 3y^2 + 9y + 3y^2 - 9y + 27 = y^3+27

Tommy Joseph · Answer 2

(y+3) (y^2 - 3y + 9) = (y+3) (y^2 + - 3y + 9) = (y) (y^2) + (y) ( - 3y) + (y) (9) + (3) (y^2) + (3) ( - 3y) + (3) (9) = y^3 - 3 y^2 + 9y + 3 y^2 - 9y + 27 = y^3 + 27
