Question

How do you combine `(4d-2) - (d+1)`?

Answer 1

`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`!)
