Chapter 6: Problem 19

Evaluate the algebraic expression for the given value or values of the variables. \(x^{2}+5 x-6 ; \quad x=4\)

Short Answer

Expert verified
The evaluated value of the expression \(x^{2}+5 x-6\) for \(x = 4\) is 30.

Step by step solution

01

Substitute the given value into the expression

Replace the variable x in the algebraic expression \(x^{2}+5 x-6\) by the given value 4. This gives: \(4^{2}+5 * 4-6\)
02

Perform the calculations

First, square 4 which gives \(16\). Next, multiply 5 by 4 which equals \(20\). Subtract 6 from the sum of these two results. This gives: \(16+20-6 = 30\)
