Essential you need to multiply by the reciprocal. Division of a rational expression are similar to fractionsFor dividing rational expressions you will use the same method as you used for dividing numerical fractions.
Lets begin by recalling division of numerical fractions. Here are the steps required for Dividing Rational Expressions. Keep in mind that the result of dividing rational expressions will only be.
Using this approach we would rewrite1xx23 as the product1x3x2. It discusses the keep change flip princ. Rational expressions are fractions.
Keep the first rational expression change the division sign to multiplication and flip the numerator and denominator of the second rational expression. Specifically to divide rational expressions keep the first rational expression change the division sign to multiplication and then take the reciprocal of the second rational expression. Change the division sign to a multiplication sign and flip or reciprocate the fraction after the division sign.

To divide a rational expression by another rational expression multiply the first expression by the reciprocal of the second. For dividing rational expressions you will use the same method as you used for dividing numerical fractions. Here as you see i have factored the different expressions and cancelled the common expression finally it gets reduced to nothing.
