Here is another example: example: f (x) = (8x 3 2x 2 − 5x 1) (2x 3 15x 2) the degrees are equal (both have a degree of 3) just look at the leading coefficients of each polynomial: top is 8 (from 8x 3) bottom is 2 (from 2x 3) so there is a horizontal asymptote at 8 2 = 4. Learn how to simplify, manipulate, and solve rational expressions, equations, and functions with khan academy's interactive videos and exercises. A rational expression is an expression of the form p (x) q (x), where p and q are polynomials and q ≠ 0. remember, division by 0 is undefined. here are some examples of rational expressions: − 13 42 7y 8z 5x 2 x2 − 7 4x2 3x − 1 2x − 8. notice that the first rational expression listed above, − 13 42, is just a fraction.

Divide rational expressions. to divide rational expressions we multiply the first fraction by the reciprocal of the second, just like we did for numerical fractions. remember, the reciprocal of a b is b a. to find the reciprocal we simply put the numerator in the denominator and the denominator in the numerator. we “flip” the fraction. 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. let’s begin by recalling division of numerical fractions. 2 3 ÷ 5 9 = 2 3 ⋅ 9 5 = 18 15 = 6 5.
