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?
