Procedure for Determining Undefined Rational Expressions
To determine the specific values for which a rational expression is undefined, follow these steps:
- Set the expression in the denominator equal to .
- Solve the resulting equation for the variable.
The solutions obtained from this equation represent the values that make the original rational expression undefined, as they would result in division by zero.
