What term describes a fraction that has a variable or variable expression?

What term describes a fraction that has a variable or variable expression?

rational expression. Rational expression refers to a fraction in which the numerator and denominator are polynomials. Polynomials are variables. So therefore rational expression is the answer to the term that describes a fraction that has a variable or variables expression in its numerator and it denominator or both.

What is the name of a fraction with a polynomial in its numerator and denominator?

A rational fraction is an algebraic fraction whose numerator and denominator are both polynomials.

What is it called when you factor and divide terms on the numerator and denominator of a rational function?

A rational expression is a quotient of two polynomials, where the polynomial in the denominator is not zero. Rational expressions can often be simplified by removing terms that can be factored out of the numerator and denominator. Rational expressions can be divided by one another.

What are rational expressions?

What is a rational 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 the first step in simplifying rational algebraic expression?

The first step in simplifying a rational expression is to determine the domain, the set of all possible values of the variables. The denominator in a fraction cannot be zero because division by zero is undefined.

How do you write a rational expression?

To write a rational expression in lowest terms, we must first find all common factors (constants, variables, or polynomials) or the numerator and the denominator. Thus, we must factor the numerator and the denominator. Once the numerator and the denominator have been factored, cross out any common factors.

How do you divide fractions with variables?

To divide algebraic fractions, invert the second fraction and multiply it by the first fraction. Factorise the numerators and denominators. Then cancel the factors common to both the numerator and denominator before applying multiplication to obtain the answer.
