How do you expand and simplify (x − 6)(x + 2y)^2

start of by expanding the braquet which has got a power(x + 2y) (x + 2y) = X2 + 2xy + 2xy + 4Y2then simplify that => x2 + 4xy + 4y2then multiply that by (x - 6) (x - 6) (x2 + 4xy + 4y2) = x3 + 4x2y + 4xy2 - 6x2 - 24xy - 24y2then simplify it (in this case this is as simplified as it gets x3 + 4x2y + 4xy2 - 6x2 - 24xy - 24y2
