# Evaluating Rational Expressions

1. Similar to the expressions above, try evaluating each the following rational expressions below for these three values: $$x=2$$, $$x=-3$$, and $$x=-6$$.
1. $$\dfrac{x^2+5}{x-2}$$
2. $$\dfrac{x^2+2x}{x+3}$$
3. $$\dfrac{x^2+3x+5}{x^2+2x-8}$$
1. Are there any values that don’t “work” for one or more of the expressions? If so, which values and why?
