RATL 3 | Lesson 1 | Practice (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 $$x=-6$$.

a) $$\Large \frac{x^2+5}{x-2}$$

b) $$\Large \frac{x^2+2x}{x+3}$$

c) $$\Large \frac{x^2+3x+5}{x^2+2x-8}$$

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