Evaluate the algebraic expression for the given value of the variable. \[ x^{2}-22 ; x=-4 \] For $x=-4, x^{2}-22=$ (Type an integer or a simplified fraction.)

Step 1 ：The question is asking to substitute the value of x in the given algebraic expression and then simplify it. The algebraic expression is \(x^{2}-22\) and the given value of x is -4. So, we need to substitute -4 in place of x in the expression and then simplify it.

Step 2 ：Substitute x = -4 into the expression, we get \((-4)^{2}-22\).

Step 3 ：After simplifying, we get -6.

Step 4 ：So, the result of the algebraic expression \(x^{2}-22\) for \(x=-4\) is \(\boxed{-6}\).
