RATIONAL EXPRESSION

A rational expression is an algebraic expression of the form P/Q, where P and Q are simpler expressions (usually polynomials), and the denominator Q is not zero. We can manipulate rational expressions in the same way that we manipulate fractions.

Thinking back to when you were dealing with whole number fractions one of the first things you did was simplify them: You "cancelled off" factors which were in common between the numerator and denominator. You could do this because dividing any number by itself gives you just "1", and you can ignore factors of "1".To simplify a rational expression, we first factor both the numerator and denominator completely then reduce the expression by cancelling common factors. A rational expression can be simplified or reduced to lowest terms if all common factors from the numerator and denominator are canceled.
