Can someone help simplify this math problem?

What is the simplified answer of: 3b^3 - b[6 - 5(b + 1) - b]

Update:

I answered with b(3b^2+6b-1) but my teacher said it wasn't simplified...

    First expand, the add like terms.

    so we go: 3b^3 - 6b + 5b^2 + 5b +b^2

    3b^3 + 6b^2 - b

    or factoring out b,

    b(3b^2 + 6b -1)
