Simplifying Polynomials Using the Distributive Property

This video tutorial teaches how to simplify polynomials using the distributive property. It begins with a review of the distributive property, followed by several example problems that demonstrate how to apply the property and combine like terms. The tutorial covers both basic and advanced problems, emphasizing the importance of showing work and understanding the role of coefficients and constants. The video concludes with a summary of key concepts and encourages students to practice the techniques learned.

What is the result of combining the constants -16 and 21 in the final example?

• -5

• 5

• -37

• 37

What is the standard form of the expression x^2 - 7x + 5?

• 5 - 7x + x^2

• x^2 + 5 - 7x

• -7x + 5 + x^2

• x^2 - 7x + 5

Why is it important to write expressions in standard form?

• It makes them easier to read

• It changes the value of the expression

• It is required for all math problems

• It simplifies the calculation
