Multiplying Polynomials

This lesson teaches how to multiply polynomials using methods similar to multiplying whole numbers. It covers exponent basics, common errors, and the commutative property. The video demonstrates multiplying monomials with trinomials and trinomials with binomials, emphasizing the importance of arranging terms in descending order. It concludes with the closure property, ensuring that the product of two polynomials is always a polynomial.

What is a common misunderstanding when multiplying terms with exponents?

• Dividing the exponents

• Subtracting the exponents

• Multiplying the exponents

• Adding the exponents

When multiplying exponential terms, what should you do if you're unsure?

• Subtract the exponents

• Expand the terms

• Add the coefficients

• Ignore the variables

What is the result of multiplying 2a cubed by 5a?

• 10a to the fifth
