What is a defined rational expression?
Definitions: A rational expression is the ratio of two polynomials. If f is a rational expression then f can be written in the form p/q where p and q are polynomials.
What is undefined math example?
An expression in mathematics which does not have meaning and so which is not assigned an interpretation. For example, division by zero is undefined in the field of real numbers.
What is the undefined symbol in math?
If a sequence (an)∞n=m is not converging to any real number, we say that the sequence (an)∞n=m is divergent and we leave limn→∞an undefined. By other hand, in Computer science there are some symbols: undefined, null and NaN (not a number).
What is an example of a undefined expression?
A rational expression is undefined when the denominator is equal to zero. To find the values that make a rational expression undefined, set the denominator equal to zero and solve the resulting equation. Example: 0 7 2 3 x x − Is undefined because the zero is in the denominator.
What is rational expression undefined?
A rational expression is undefined when the denominator is equal to zero. To find the values that make a rational expression undefined, set the denominator equal to zero and solve the resulting equation.
Is the best definition of rational algebraic expression?
A rational expression is simply a quotient of two polynomials. Or in other words, it is a fraction whose numerator and denominator are polynomials.
What is defined in math?
In geometry, defined terms are terms that have a formal definition and can be defined using other geometrical terms.
What does defined mean in math?
In mathematics, a well-defined expression or unambiguous expression is an expression whose definition assigns it a unique interpretation or value.
What does it mean to make an expression undefined?
An expression in mathematics which does not have meaning and so which is not assigned an interpretation. For example, division by zero is undefined in the field of real numbers. SEE ALSO: Ambiguous, Complex Infinity, Directed Infinity, Division by Zero, Ill-Defined, Indeterminate, Well-Defined.
What are the steps in solving rational expressions?

What constitutes a rational expression?
A rational expression is nothing more than a fraction in which the numerator and/or the denominator are polynomials. Here are some examples of rational expressions. The last one may look a little strange since it is more commonly written 4×2 +6x−10 4 x 2 + 6 x − 10.
