Algebraic Operations and Exponents

The video tutorial covers Unit 7, focusing on multiplying, adding, and dividing polynomials. It begins with a review of the laws of exponents, including negative and zero exponents, and how to handle multiplication and division of terms with the same base. The tutorial includes problem-solving examples to illustrate these concepts. It also covers simplifying radicals, both manually and using a calculator, and concludes with a detailed explanation of multiplying polynomials, including perfect square trinomials.
