- A.REI.4a: Use a method of completing the square to transform any quadratic equation in x into an equation of the form (x-p)^2 = q that has the same solutions. Derive the quadratic formula from this form.
- A.REI.4b.: Solve quadratic equations in one variable. Solve quadratic equations by inspection taking square roots, completing the square, the quadratic formula, and factoring as appropriate to the initial form of the equation.
Essential Question:- How are quadratic functions used to model, analyze, and interpret mathematical relationships?
