Chapter 6: Problem 8

Evaluate the algebraic expression for the given value or values of the variables. \(x^{2}-11 ; \quad x=-3\)

Short Answer

Expert verified
The value of the algebraic expression \(x^{2}-11\) when \(x=-3\) is -2

Step by step solution

01

Substitute the value for x.

Replace \(x\) in the expression \(x^{2}-11\) by the given value \(x=-3\) so it becomes \((-3)^{2}-11\)
02

Evaluate the Exponent

An exponent is a quantity representing the power to which a given number is to be raised. Thus \((-3)^{2}\) gives the value of 9.
03

Subtract 11

With the value from the previous step, subtract 11, so we have \(9 - 11 = -2\)
