Question

evaluate the expression when m=5.
$m^2 - 5m + 3$

Explanation:

Step1: Substitute \( m = 5 \) into the expression

We substitute \( m = 5 \) into \( m^2 - 5m + 3 \), so we get \( 5^2 - 5\times5 + 3 \).

Step2: Calculate each term

First, calculate \( 5^2 = 25 \), then \( 5\times5 = 25 \). Now the expression becomes \( 25 - 25 + 3 \).

Step3: Simplify the expression

\( 25 - 25 = 0 \), then \( 0 + 3 = 3 \).

Answer:

\( 3 \)
