How To Know When To Use The Quadratic Formula

Solving General Quadratic Equations by Completing the Square We can complete the square to solve a Quadratic Equation (find where it is equal to zero). But a general Quadratic Equation can have a coefficient of a in front of x 2 :

  • A(8)(A) solve quadratic equations having real solutions by factoring, taking square roots, completing the square, and applying the quadratic formula Resource Objective(s) Given a quadratic equation, the student will solve the equation by factoring, completing the square, or by using the quadratic formula.
  • This is actually a very good question, but not one with a really definitive answer. The following is mostly some rules of thumb. If the quadratic looks particularly " ugly" use the quadratic formula.
  • A quadratic equation is allowed (but not required) to have an $\,x\,$ term. The coefficient $\,b\,$ might be zero, which means the $\,x\,$ term is gone. A quadratic equation is allowed (but not required) to have a constant term.
  • Vertex Form. Let's use a vertex that you are familiar with: (0,0). Use the following steps to write the equation of the quadratic function that contains the vertex (0,0) and the point (2,4).
