Multiplying and Simplifying Expressions

This video tutorial covers the multiplication of binomials and trinomials using the area model and FOIL method. It provides examples of each method, explains special cases like zero terms, and demonstrates how to find shaded regions using polynomial multiplication. The video emphasizes the importance of writing answers in standard form and combining like terms.

What is the purpose of using the FOIL method in multiplying binomials?

• To simplify the expression

• To organize the multiplication process

• To add the terms together

• To divide the terms

In the area method, what shape is used to organize the multiplication of binomials?

• Square

• Circle

• Triangle

• Rectangle

When using the FOIL method, what does the 'O' stand for?

• Outer

• Order

• Over

• Open

What happens to like terms when simplifying expressions after using the FOIL method?

• They are combined

• They are divided

• They are subtracted

• They are multiplied

What is the result of multiplying x by x in the expression (x + 2)(x + 4)?

• 2x

• 4x

• x^2

• x

How do you express (x + 4)^2 using binomials?

• (x + 4)(x - 4)

• (x + 2)(x - 2)

• (x + 4)(x + 4)

• (x + 2)(x + 2)

What is the first step in finding the area of a shaded region?

• Add the areas

• Multiply the areas

• Subtract the smaller area from the larger area

• Divide the areas

In the expression 2x + 7 times 9x - 2, what is the result of 2x times 9x?

• 18x^2

• 18x

• 9x

• 9x^2

What is the final simplified form of the expression 18x^2 + 59x - 14 - 3x^2 - 36x?

• 15x^2 + 59x - 14

• 15x^2 + 23x - 14

• 18x^2 + 59x - 36x

• 18x^2 + 23x - 14
