Adding and Subtracting Polynomials Explained

This video tutorial covers the process of adding and subtracting polynomials. It begins with an introduction to like terms, which are terms with the same variable and exponent that can be combined. The tutorial then provides three examples, each progressively more complex, demonstrating how to handle parentheses and apply the distributive property. The video emphasizes the importance of combining like terms and ordering terms by their exponents.

What are like terms in polynomials?

• Terms with the same variable and the same exponent

• Terms with the same variable but different exponents

• Terms with no variables

• Terms with different variables and exponents

How do you handle a negative sign in front of parentheses when simplifying polynomials?

• Ignore the negative sign

• Multiply by negative one outside the parentheses only

• Consider it as a negative one and distribute

• Add one to each term inside
