EXPLANATION(S)
I've complied some of the informations about RATIONAL ALGEBRAIC EXPRESSION from trusted sources here:
A rational algebraic expression (or rational expression) is an algebraic expression that can be written as a quotient of polynomials, such as x2 + 4x + 4. An irrational algebraic expression is one that is not rational, such as √x + 4.
Rational expressions are fractions that have a polynomial in the numerator, denominator, or both. ... Remember that you can't divide by zero, so this means that for the expression xx−2 x x − 2 , x cannot be 2 because it will result in an undefined ratio.
Examples of rational expression are 5/x − 2, 4/(x + 1), (x + 5)/5, (x2 + 5x + 4)/(x + 5), (x + 1)/(x + 2), (x2 + x + 1)/2x etc.
