# RATL 3 | Lesson 1 | Solutions (Evaluating Rational Expressions)

Solutions:

1)

a). for $$x = 2$$, solution is undefined; for $$x = -3$$, solution is $$\large\frac{-14}{5}$$; $$x= -6$$, solution is $$\Large\frac{-41}{5}$$

b). for  $$x = 2$$, solution is $$\Large\frac{8}{5}$$;  for $$x = -3$$, solution is undefined; for $$x = -6$$, solution is -8

c). for $$x = 2$$, solution is undefined; for $$x = -3$$, solution is -1; for $$x = -6$$, solution is $$\Large\frac{23}{16}$$

2).  Any time there is a zero in the denominator, there is no solution for that value of x.
