Factoring using the quadratic formula and completing the square. The simplest Quadratic Equation is. Given a general quadratic equation of the form.
The quadratic equation can be written in three different forms.
A quadratic equation can be solved by drawing the equation on a graph and seeing where the curve crosses the x-axis. Pick a value of x and calculate y to get points and graph the parabola. To solve quadratic equation by graphing we have to write the given quadratic equation as a quadratic function as shown below. The quadratic equation can be written in three different forms.
