Quadratic Equations are useful in many other areas: For a parabolic mirror, a reflecting telescope or a satellite dish, the shape is defined by a quadratic equation. Quadratic equations are also needed when studying lenses and curved mirrors. And many questions involving time, distance and speed need quadratic equations. Sometimes you are asked to solve a quadratic equation using completing the square. This means you first need to get the quadratic equation into the Square form, then solve. Here is a few examples. The detailed step to go to the square form are found here so for the below examples, we will just briefly outline the steps. SOLVING QUADRATIC EQUATIONS WITH THREE TERMS We will now deal with the equation ax2 + bx + c = 0 in which neither a nor b nor c are zero. There are three basic methods of solving such quadratic equations: • by factoring • by completing the square • by the quadratic formula Completing the square is an effective way to solve a quadratic equation.

(a) Use the process of factoring and completing the square in a quadratic function to show zeros, extreme values, and symmetry of the graph, and interpret these in terms of a context. A.SSE.3a. Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression. (a)Factor a quadratic expression to reveal the zeros of the function it defines. Solve x2 + 12x = -20 by completing the square. Add to both sides of the equation. The value of in this equation is . Write the left side of the equation as a binomial squared. The left side of the equation becomes ()2. Use the square root property of equality. Isolate the variable: x = So that we can put that into practice, let me once again describe how to solve the quadratic. Let y=x+a/2. Then y satisfies a quadratic equation of the particularly simple form y 2 +C=0. Once we have solved this equation for y, it is easy to obtain a solution of the original equation for x, since x is a very simple linear function of y.
