Question

Evaluate the expression for d = –2 and f = –3.

df − f =

Answer 1

To evaluate the expression \( df - f \) for \( d = -2 \) and \( f = -3 \), we start by substituting the values of \( d \) and \( f \) into the expression.

1. Calculate \( df \):
\[
df = (-2)(-3) = 6
\]

2. Now we can substitute \( df \) and \( f \) into the expression:
\[
df - f = 6 - (-3)
\]

3. Simplify the expression:
\[
6 - (-3) = 6 + 3 = 9
\]

Thus, the value of the expression \( df - f \) is \( 9 \).
