This video tutorial covers the basics of polynomials, including monomials, binomials, and trinomials. It explains how to determine the degree of a polynomial and how to write polynomials in standard form. The video also provides practice problems for adding and subtracting polynomials, emphasizing the concept of a closed set. A story problem is included to illustrate the application of these concepts in real-world scenarios.

What is a monomial?

• A polynomial with two terms

• A single term, possibly with coefficients and exponents

• A polynomial with three terms

• A term with a variable in the denominator

What determines the degree of a monomial?

• The sum of the exponents of its variables

• The number of terms it contains

• The sum of the coefficients

• The highest coefficient value

What is the leading coefficient in a polynomial in standard form?

• The coefficient of the term with the highest exponent

• The constant term

• The coefficient of the first term listed

• The coefficient of the term with the lowest degree

Which of the following is a binomial?

• 2x^3

• x^2 - x + 3

• 3x^2 + 5

• 4x

How do you write a polynomial in standard form?

• List terms randomly

• Arrange terms from highest to lowest degree

• Arrange terms from lowest to highest degree

• Arrange terms alphabetically

What type of polynomial is 7x^3 - 2x + 5?

• Trinomial

• None of the above

• Binomial

• Monomial

What does it mean for a set of polynomials to be 'closed' under addition?

• The result of addition is always zero

• The set excludes certain polynomial forms

• The addition of two polynomials yields another polynomial

• The set is limited to a finite number of polynomials

When subtracting polynomials, what must you remember about the signs of the terms?

• Signs are switched for terms being subtracted

• Only the signs of the constant terms are switched

• No signs are switched

• All signs must be switched

In the context of the story problem, what does the polynomial represent?

• The time it takes for the objects to hit the ground

• The distance between the two objects over time

• The speed of the falling objects

• The total height of both objects

What happens to the distance between the penny and the paintbrush over time?

• It remains constant

• It increases by 40 feet per second

• It fluctuates unpredictably

• It decreases by 40 feet per second
