The quadratic formula is. 1 to factor the quadratic equation if you can do so 2 to use the quadratic formula or 3 to complete the square. Earlier we factored this polynomial by splitting the middle term.
There are three basic methods for solving quadratic equations.
Let us now solve the equation by Completing The Square and by using the Quadratic Formula Parabola Finding the Vertex. Solving quadratic equations by graphing. To solve a quadratic equation by factoring Put all terms on one side of the equal sign leaving zero on the other side. Starting with a quadratic equation in standard form ax2 bx c 0 Divide each side by a the coefficient of the squared term.
