How to solve quadratic equations by completing square trinomials?
We need another method for solving quadratic equations. The method we shall study is based on perfect square trinomials and extraction of roots. The method is called solving quadratic equations by completing the square. Consider the equation x2 + 6x + 5 = 0.
How to find the perfect square of a quadratic equation?
Remember that for a perfect square, the quadratic must have 40 PARTI MODELING FOR PROCESS DYNAMICS the form s 2 + as + (all) 2 = (s + a/2) 2 , where the constant is one-half the mid¬ dle coefficient squared.
How to complete x 2 + b x into a perfect square?
It shows us that in order to complete x 2 + b x into a perfect square, where b is any number, we need to add ( b 2) 2 to it. For example, in order to complete x 2 + 6 x into a perfect square, we added ( 6 2) 2 = 9 to it. All right! Now that you're a certified square-completer, let's go back to the process of solving equations using our method.
How do you solve a quadratic equation by factoring?
The method we shall study is based on perfect square trinomials and extraction of roots. The method is called solving quadratic equations by completing the square. Consider the equation x2 + 6x + 5 = 0. This quadratic equation could be solved by factoring, but we'll use the method of completing the square.
