👉 Reformulations are specific forms of mathematical expressions that involve the use of different symbols or notations to represent the same idea. These can be used in various contexts, such as in algebraic equations and calculus problems. For example, consider the equation y = x^2 + 3x - 4. In this case, we could reformulate it into a form that is easier to work with: y = (x + 1)^2 - 5 This new expression can be
