What is the last operation performed when evaluating (8 - 2x)^2 + 4 for x = 3?

Question:

What is the last operation performed when evaluating {eq}(8 - 2x)^2 + 4 {/eq} for {eq}x = 3 {/eq}?

Evaluating Expressions

Algebraic expressions can be evaluated for specific values of their variable. This is why such expressions are important. They can be evaluated for various values of the variable and such evaluations can then be compared.

Answer and Explanation:


When evaluating the given expression, we would first calculate the value of {eq}(8 - 2x)^2 {/eq} for {eq}x=3 {/eq}. Once this value is calculated, we add it to 4. This will be the last operation.
