Beginning Algebra: Multiplying Polynomials
This lesson is part of a series: Beginner Algebra
Once you have learned to add and subtract polynomials by combining like terms, Professor Burger teaches you how to multiply polynomials. First, he covers how to multiply powers with the same base. Then, he will cover how to raise one power to another power [(x^a)^b]. Finally, Prof. Burger will show you how to multiply two binomials, making sure you distribute every term.
Taught by Professor Edward Burger, this lesson was
