3d-3

Explanation:

You distribute the negative, then combine the like terms. The "minus" outside the second parentheses is really a negative sign that applies to BOTH terms. So it would become:

4d-2-d-1

Combine like terms, making sure to carry the sign in front of each number or variable.

4d-d" " and " "-2-1

so

3d-3

3d and 3 are two separate things, so you cannot go any farther. ( do not subtract the 3 from the 3d!)
