Factoring by Grouping: Rewriting Trinomials

This lesson teaches how to rewrite trinomials by factoring using grouping. It begins with a review of multiplying linear expressions to form quadratics and then explains factoring by grouping when the leading coefficient is 1. The lesson progresses to more complex cases where the leading coefficient is not 1, detailing the steps to determine replacement terms and factor the expression. Advanced examples are provided to reinforce the core lesson, demonstrating how to handle higher-degree polynomials and different coefficients.
