Solve quadratic equations in one variable. Use the method of completing the square to transform any quadratic equation in π₯ into an equation of the form (π₯ β π)Β² = π that has the same solutions. Solve quadratic equations (as appropriate to the initial form of the equation) by: inspection of a graph, taking square roots, completing the square, using the quadratic formula, factoring. Recognize complex solutions and write them as π Β± ππ for real numbers π and π (Algebra 2 only).
