Asked by Hazel
After solving a rational equation, why is it important to check your answer? How is this done? What happens if you are checking a solution for the rational expression and find that it makes one of the denominators in the expression equal to zero?

That's why you check. If a fraction has zero denominator, it is undefined.
If b = a/0
then b*0 = a
There is no number you can multiply by 0 to get a nonzero value.
