Lesson Summary:

In this lesson, we learn how to divide a polynomial by a monomial by breaking up the numerator and putting each term over the monomial, then canceling out the common factors. We see examples of how to do this, including cases where there are fractions involved and where there are negative signs, and learn different methods of simplifying the expressions, including using the laws of exponents and prime factoring. By the end of the lesson, we are able to confidently divide polynomials by monomials.
