Answer 2

To simplify the expression (10-12y^2)-(y^3-y^2+6), we can distribute the negative sign to each term within the parentheses. This can be done as follows:

10 - 12y^2 - y^3 + y^2 - 6

Next, we can combine like terms:

(-y^3) + (-12y^2 + y^2) + (10 - 6)

Simplifying further:

-y^3 - 11y^2 + 4

Therefore, the simplified form of the expression (10-12y^2)-(y^3-y^2+6) is -y^3 - 11y^2 + 4.
