Answer:
When the numerator is zero, a rational expression is undefined. To find the values that lead to an undefined rational expression, set the denominator to zero and solve the resulting equation.
step-by-step explanation:
Any expression containing a fraction that looks like this: x/0 is undefined. The expression is also undefined when x=0 if the denominator contains a polynomial, such as 1/x.
In algebra, an expression is a mathematical statement made up of any arrangement of variables and integers and connected by an arithmetic operation.
A function, frequently written as f ( x ) = 2 x + 3 or y = 17 x, indicates that the equation has definite solutions by requiring that it equals some value. Because there are variable in the numerator, denominator, or both, the two examples above are referred to as rational expressions because irrational integers can indeed be stated as fractions and are therefore excluded from this study.
The term "undefined" is frequently used to describe a statement that lacks an ascribed meaning or value, such as an ambiguous form that has a predisposition to take on several meanings. Depending on the situation, the phrase can signify a variety of things.
