# What is Division of Rational Expressions?

Jan 5, 2015

Division of a rational expression are similar to fractions.For dividing rational expressions, you will use the same method as you used for dividing numerical fractions: when dividing by a fraction, you flip-n-multiply. For instance:

[ (x^2 + 2x - 15) / (x^2 - 4x - 45) ] ÷ [ (x^2 + x - 12) / (x^2 - 5x - 36) ]

here as you see i have factored the different expressions and cancelled the common expression finally it gets reduced to nothing

Hope this helped you
