Summary: By using a uniform formulaic approach for both linear and quadratic equations, activities such as removing parentheses, adding or subtracting the same quantity to both sides of the equation in sufficient steps to bring all ``$x$terms" to one side, and simplifying, all have a common purpose: Find a function equal to a constant. The task becomes to determine the choice of $x$ for which the value of a function is equal to that constant, whether it is zero or not. We call these values of $x$ the ``Vees" of the function. The approaches and formulas for both linear and quadratic equations are discussed.
