Dividing polynomials by monomials
This section will teach us how to divide a polynomial (more than one term) by a monomial (one term only). We will use a model to help us on the division. We will then try to solve the questions without using the model. At the end, we will look at some of the related word problems.
Basic Concepts: Understanding integer division, Equivalent expressions of polynomials, Multiplying and dividing monomials , Multiplying polynomials by monomials
