A polynomial expression is considered a rational expression when it is expressed as a fraction where both the numerator and the denominator are polynomials. For example, the expression ( \frac{x^2 + 3x + 2}{x - 1} ) is a rational expression because its numerator ( x^2 + 3x + 2 ) and denominator ( x - 1 ) are both polynomials. Rational expressions can be simplified, added, or multiplied, just like rational numbers, provided that the denominator is not zero.

How do you determine whether an expression is rational algebraic expression or not?

If the algebraic expression can be written in the form of a(x)/b(x) where a(x) and b(x) are polynomial functions of x and b(x) ≠ 0, then the expression is a rational algebraic expression.


Differentiate of polynomial and algebraic expression?

A polynomial is always going to be an algebraic expression, but an algebraic expression doesn't always have to be a polynomial. In another polynomial is a subset of algebraic expression.


How can i Differentiate between an algebraic expression and polynomial?

A polynomial is always going to be an algebraic expression, but an algebraic expression doesn't always have to be a polynomial. An algebraic expression is an expression with a variable in it, and a polynomial is an expression with multiple terms with variables in it.


How is a rational function the ratio of two polynomial functions?

That's the definition of a "rational function". You simply divide a polynomial by another polynomial. The result is called a "rational function".


What is The equation of a rational function does not have to contain a rational expression?

A rational function is defined as a function that can be expressed as the quotient of two polynomials. However, it can also be represented in forms that do not explicitly show a rational expression, such as a polynomial or a constant function, which can be thought of as a rational function with a denominator of 1. For example, the function ( f(x) = 3x^2 + 2 ) is a polynomial and can be considered a rational function because it can be rewritten as ( f(x) = \frac{3x^2 + 2}{1} ). Thus, while the standard form includes a rational expression, the definition encompasses more than just explicit fractions.
