Expand and Simplify Polynomials - Grade 9

This video is about expanding and simplifying polynomials. Two examples are presented Example 1 : -(-2x - 2)(-x+3) - (3x^2 + x - 2 ) Example 2 3(-x - 5)^2 - 4x (- x - 7 ) The above examples are solved with all the details starting with a review of multiplying monomials including multiplying exponentials with the same variables. Grouping monomials to simplify expressions is also reviewed.
