Multiplying Polynomials Part 1

​Multiplying a monomial and a trinomial

​You need to distribute the monomial!

For Example:​

Some text here about the topic of discussion

You distribute the 2x²​

Don't forget to "add" the exponents!​

Multiple Choice

In the following expression $$3x^2\left(x^2-2x-5\right)$$ , which part is the monomial?

• $$3x^2$$  

• $$x^2-2x-5$$  

Multiple Choice

In the following expression $$3x^2\left(x^2-2x-5\right)$$ , which part is the trinomial?

• $$3x^2$$
