Multiplying Binomials and Polynomials

This video tutorial by Kirk Wyler from eMath Instruction covers Unit 7, Lesson 4 on multiplying polynomials. It begins with an introduction to polynomial multiplication, focusing on the double distribution method. The lesson includes exercises demonstrating this technique, followed by a comparison of four different methods for multiplying binomials: standard multiplication, area model, FOIL, and double distribution. The tutorial concludes with methods for multiplying binomials with trinomials, using both area models and double distribution.

What is the primary method discussed for multiplying binomials?

• Single distribution

• Double distribution

• Quadruple distribution

• Triple distribution

When using double distribution, what do you do after multiplying the first term of the first binomial?

• Divide the terms

• Add the terms

• Multiply the second term of the first binomial

• Subtract the terms

What is the result when multiplying two linear binomials?

• A monomial

• A binomial

• A trinomial

• A quadrinomial

Which method is NOT one of the four techniques for multiplying binomials?

• Subtraction method

• FOIL

• Area model

• Standard multiplication

What happens to the middle terms when using the FOIL method?

• They are combined

• They are subtracted

• They are divided

• They are ignored

Which method is most commonly used for multiplying binomials?

• FOIL

• Standard multiplication

• Area model

• Double distribution

In the area model, where do the like terms typically align?

• Horizontally

• Randomly

• Vertically

• Diagonally

What is the first step when multiplying a binomial by a trinomial using double distribution?

• Subtract the trinomial from the binomial

• Add all terms together

• Multiply the trinomial by the first term of the binomial

• Divide the trinomial by the binomial

What is a disadvantage of the area model?

• It is too fast

• It is not accurate

• It takes up a lot of space

• It is too simple

What is the key strategy when multiplying three polynomials together?

• Divide the first polynomial by the second

• Add all polynomials together

• Find the product of two first, then multiply by the third

• Multiply all three at once
