# How To: Divide rational expressions containing trinomials

In this video the instructor shows how to divide rational expressions that contain trinomials. A division containing two fractions can always be turned into a multiplication by multiplying the first fraction by the reciprocal of the second fraction. This way any division can be turned into a multiplication problem and solved easily. Now after you convert the division into multiplication factorize the equations. Now you can factorize the equations by splitting the middle term and grouping it into two terms. After factorizing all the equation in the given rational expression cancel out the common terms in the numerator and the denominator. Now after the common terms gets canceled you are left with the simplified expression. This video shows how to divide rational expressions that contain equations of the third degree.
