Did I do this problem right?

(2y+5w+6)(5y+5w-4)

2y(5y)+ 2y(5w) + 2y(-4) + 5w(5y) + 5w(5w)+ 5w(-4) + 6(5y) + 6(5w) + 6(-4)

then I multiplied:

10y^2 + 10wy - 8y + 25wy + 25w^2 - 20w + 30y + 30w - 24

then I combined like terms:

10y^2 + 15wy + 25w^2 + 22y + 10w - 24

final answer:

10y^2 + 25w^2 + 15wy + 22y + 10w-24
