This math topic focuses on factoring quadratic equations by removing a common factor. It is part of a broader unit on the factoring of quadratics, aimed at making the process more manageable by initially simplifying the equations. Each problem presents a quadratic in standard form, and the task is to identify and factor out the greatest common factor, simplifying the expression for easier further handling. The worksheet includes multiple-choice questions with given answers in varying factored forms to assess the understanding of the concept. This practice is essential for algebra students learning about polynomials and their factorization.
