Chapter 6: Problem 20

Evaluate the algebraic expression for the given value or values of the variables. \(x^{2}+7 x-4 ; \quad x=6\)

Short Answer

Expert verified

The evaluated expression for \(x=6\) is 74

Step by step solution

Substitute the Given Value into the Expression

Replace \(x\) in the provided expression with the given value \(x=6\). The expression \(x^{2}+7 x-4\) thus becomes: \(6^{2}+7*6-4\)

Calculate the Expression

Following the BIDMAS/BODMAS rule: Brackets, Indices/Orders, Division and Multiplication, and Addition and Subtraction, the expression simplifies to: \(36 + 42 - 4\)

Simplify the Expression Further

The subtraction and addition operations give a final result of: \(36 + 42 - 4 = 74\)
