-2(y)^3(w+2)^2 in expanded form

-2(y)^3(w+2)^2 in expanded form


I got -2y^3 w^2 + 2w +2w + 4

= -2y^3 w^2 + 4w + 4?

Or do I just leave it at -2y^3 w^2 + 2w +2w + 4?

Or did I do it totally wrong?

-2y³(w+2)²
-2y³ (w² + 4w + 4)
-2w²y³ - 8wy³ - 8y³
(this would be the expanded form)

you have it correct i believe, i think you are just missing a plus sign

-2y^3 + w^2 + 4w + 4 is correct
