Question
Simplify each complex rational expression. In each case, list any values of the variables for which the fractions are not defined.$\frac{b-\frac{1}{b}}{\frac{1}{b}-1}$
Step 1
We can do this by multiplying the numerator and denominator by $b$. This gives us: \[\frac{b^2-1}{1-b}\] Show more…
