Rewrite in simplest terms
-4w -9(-4w +9)
One way to simplify this expression is to distribute the negative sign that is in front of the parenthesis to each term inside the parenthesis.
-4w - 9(-4w + 9) can be written as -4w -1*(-4w) -1*9.
This further simplifies to -4w + 4w - 9.
Since -4w and 4w are like terms and add up to 0, we are left with - 9 as the simplest term.
