Adding and Subtracting Polynomials

This video tutorial covers the addition and subtraction of polynomials without like terms. It begins with an introduction to combining polynomials and reviews polynomial addition with examples. The tutorial then explains polynomial subtraction, addressing common misunderstandings, and introduces the standard form of polynomials. It demonstrates adding polynomials using standard form and tables, and concludes with using tables for polynomial subtraction. The lesson ends with a summary of key points.

What is the main focus of this lesson on polynomials?

• Solving polynomial equations

• Adding and subtracting polynomials without like terms

• Dividing polynomials

• Multiplying polynomials

When adding polynomials, what should you do with like terms?

• Combine them

• Divide them

• Multiply them

• Ignore them

In polynomial subtraction, what is a common mistake?

• Combining terms based on location

• Combining terms based on degree

• Ignoring the constant term

• Multiplying terms instead of subtracting

How should terms be arranged in the standard form of a polynomial?

• In alphabetical order

• In descending order by degree

• In ascending order by degree

• In random order

What is the exponent of a variable without an explicit exponent?

• Three

• Two

• One

• Zero

What is the purpose of adding placeholders like 0x squared in polynomials?

• To change the polynomial's value

• To make the polynomial longer

• To simplify the polynomial

• To ensure all degrees are represented

What method can be used to add polynomials besides vertical addition?

• Using a computer program

• Using a calculator

• Using a table

• Using a graph

When combining like terms in a table, what should you do if a column has only one term?

• Ignore it

• Multiply it by zero

• Leave it as is

• Add a zero to it

What happens to the constant term when x is raised to the zero power?

• It becomes zero

• It remains unchanged

• It doubles

• It is eliminated

In the example 5x cubed plus 8x squared minus 7, what happens when you add 4x cubed minus 2x minus 3?

• The terms are multiplied

• The terms are subtracted

• The like terms are combined

• The terms are divided
