Full solution

Q. Simplify the expression:

\newline

-2(-2d) =

_____

Distribute $-2$ : First, we gotta distribute the $–2$ across the $–2d$ , so like, $–2$ times $–2d$ .
Multiply $-2d$ : That's gonna be $4d$ , cause a negative times a negative is a positive.
Simplify to $4d$ : So the simplified expression is $4d$ .
