This math topic focuses on practicing polynomial algebra specific to the difference of squares with integers. The format involves calculating expressions in the form \(\frac{a^2 - b^2}{a}\) without using a calculator. Each question provides an expression based on this algebraic concept and multiple-choice answers. The broader context of these problems is Polynomials and Quadratics at an advanced level. The exercise is designed to enhance algebraic manipulation skills, particularly involving the difference of squares formula and simplification techniques.
