Exploring Adding and Subtracting Polynomials

This video tutorial covers the basics of adding and subtracting polynomials. It begins with an introduction to polynomials, explaining their components such as variables and whole numbers. The tutorial then demonstrates how to add polynomials by combining like terms and performing arithmetic operations. It also covers subtracting polynomials, emphasizing the importance of distributing terms correctly. A complex example is provided to illustrate multiple polynomial operations, including handling exponents and combining terms. The video concludes with additional resources for further learning.

What is a polynomial?

• A series of numbers added together without any variables.

• A mathematical expression that includes variables raised to positive whole numbers and their coefficients.

• An equation with a single variable to the power of one.

• A function that only includes variables with negative exponents.

How do you combine like terms in a polynomial?

• By adding the exponents of the terms.

• By dividing the polynomial by the number of terms.

• By multiplying the coefficients of the terms.

• By adding the coefficients of the terms with the same variable and exponent.

What happens when you distribute a negative number across a polynomial?

• The coefficients of all terms are divided by the negative number.

• The exponents of all terms are decreased by one.
