To determine the values that make a rational expression undefined, set the denominator (bottom part of the fraction) equal to zero and solve the equation. The values of the variables that make the denominator zero are the values that make the rational expression undefined.
To determine the values that make a rational expression undefined, identify the values that would result in division by zero in the expression. These values are the ones that make the denominator equal to zero, which indicates undefined behavior in the rational expression.
To determine the values that make a rational expression undefined, find the values that make the denominator equal to zero. These values are the ones that result in division by zero, which is undefined in mathematics.
