Question

Find the value of this expression if x=-2. X^2+8/x -2

Answer 1

Recall that to evaluate an expression at a given value, we substitute the variable by the given value.

Therefore, evaluating the given expression at x=-2 we get:

$(-2)^2+\frac{8}{-2}-2.$

Simplifying the above result we get:

$\begin{gathered} 4-4-2, \\ -2. \end{gathered}$

Answer:

$-2.$
