A fraction is undefined when the denominator is ZERO.

If the fraction is an algebraic fraction we need to determine

the value of the variable that makes only the denominator ZERO.

The steps for doing are:

1. Set the denominator equal to ZERO

2. Solve for the variable. NOTE that if the

denominator is a quadratic equation, there will

be two values that make the equation undefined.
