# Evaluating Rational Expressions

- Similar to the expressions above, try evaluating each the following rational expressions below for these three values: \(x=2\), \(x=-3\), and \(x=-6\).

- \(\dfrac{x^2+5}{x-2}\)
- \(\dfrac{x^2+2x}{x+3}\)
- \(\dfrac{x^2+3x+5}{x^2+2x-8}\)

- Are there any values that don’t “work” for one or more of the expressions? If so, which values and why?
