Free lessons, worksheets, and video tutorials for students and teachers. topics in this unit include: equivalent expressions, restrictions, multiplying and dividing rational expressions, adding and subtracting rational expressions, and rational exponents. this follows chapter 2 of the grade 11 functions mcgraw hill textbook and chapter 2 of the. 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. Section 1.6 : rational expressions. for problems 1 – 3 reduce each of the following to lowest terms. x2−6x −7 x2 −10x 21 x 2 − 6 x − 7 x 2 − 10 x 21 solution. x2 6x 9 x2 −9 x 2 6 x 9 x 2 − 9 solution. 2x2−x −28 20−x −x2 2 x 2 − x − 28 20 − x − x 2 solution. for problems 4 – 7 perform the indicated.

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. Solving rational equations. an equation that contains at least on rational expression is called a rational equation. you solve a rational equation as you solve any other equation. example. x − 3 2x 3 x = 5 ⇒ x − 3 2x 2 ⋅ 3 2 ⋅ x = 5 ⇒ x − 3 2 x 3 x = 5 ⇒ x − 3 2 x 2 ⋅ 3 2 ⋅ x = 5 ⇒.
