To simplify the expression \((-2f - 2) + (4f + 6)\), follow these steps:
-
Remove the parentheses: \[ -2f - 2 + 4f + 6 \]
-
Combine like terms. First, combine the \(f\) terms: \[ -2f + 4f = 2f \]
-
Then, combine the constant terms: \[ -2 + 6 = 4 \]
-
Put it all together: \[ 2f + 4 \]
So, the simplified expression is: \[ \boxed{2f + 4} \]
