The Algebra of Rational Functions
Lecture no. 29 from the course: Algebra II
Taught by Professor James A. Sellers | 31 min | Categories: The Great Courses Plus Online Mathematics Courses
Combine rational functions using addition, subtraction, multiplication, division, and composition. The trick is to start each problem by putting the expressions in factored form, which makes the calculations go more smoothly. Leaving the answer in factored form also allows other operations, such as graphing, to be easily performed.
