This section will teach us how to multiply a polynomial (more than one term) by a monomial (one term only). We will use an area model as an aid to do the multiplication. 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 ,

Related concepts: Multiplying monomial by monomial, Multiplying monomial by binomial, Multiplying binomial by binomial, Multiplying polynomial by polynomial,

- 1.Multiply each expression by using an area model.a)$\left( {3x} \right)\left( {7x + 4} \right)$b)$\left( {2x + 8} \right)\left( {1.6x} \right)$
- 2.Multiply.a)$\left( {4.6} \right)\left( {3x - 8} \right)$b)$\left( {5x} \right)\left( {2x - 1.2} \right)$c)$\left( {4x - 1} \right)\left( {6x} \right)$d)$\left( {13 - 9x} \right)\left( {2.3x} \right)$e)$\left( {3x} \right)\left( {2x + 5y + 7} \right)$f)$\left( {\frac{1}{4}x - 2} \right)\left( { - x} \right)$
