Any algebraic expression, that is a quotient of two other algebraic expressions, is called a rational algebraic expression. Thus if P and Q are algebraic expressions and Q ¹ 0 then the expression    is called a rational algebraic expression.

We say that a rational algebraic expression is meaningless for those values of the variable for which the denominator Q is zero.

To simplify rational algebraic expressions, we may be required to factorize algebraic expressions in the numerator and /or denominator.
