<h1>Use online help to solve equations</h1><strong> Author: <a href='http://www.articleseen.com/profile_mahan.aspx'>mahan</a></strong><br /><p><p>Friend's today we are going to learn the basic concepts behind Quadratic equations and how to solve a Quadratic equation in a better and faster manner. The first question comes in our mind is what is a quadratic equation? And the answer for the same is a polynomial equation of the second order is known as Quadratic equation. The general form of quadratic equation is written as :</p> <p>ax² + bx + c = 0</p> <p>where x is a variable and a, b and c are constants. Here a is quadratic coefficient, B is a linear coefficient and c is a constant term or we can say that it is a free term.</p> <p>Factoring, completing the squares, graphing, Newton's method, and with the help of Quadratic formula are the methods through which we can solve our Quadratic equations.</p> <p>Quadratic formula comes from the following: Quadratic equation is ax² + bx + c = 0 and it has the solution</p> <p>x = -b±root of squared b – 4ac/ 2a</p> <p>The expression within root is known as discriminant of the quadratic equation. Discriminant is denoted by the upper case Greek letter delta.</p> <p>Delta = squared b – 4ac .</p> <p>If the discriminant is zero then there is only one exact real root, also known as double root. X = -b/</p> <p>2a.</p> <p>The</p> <p>‘±’ symbol indicates ‘plus or minus’, which means that we need to work out the formula twice, once with a plus sign in that position, then again with a minus sign. Let's take an example of Quadratic equation : x² - 4x - 5 = 0 , here no coefficient is written before x so we can use 1 as a coefficient of x. Now here a = 1, b = -4, and c = -5 now substitute this values in the above equation we get two values for the same that is x = 5 or x = </p> <p> -1.</p> <p>Quadratic</p> <p> equation is also an Algebraic expression, and by using the methods of solving Quadratic equation we can solve algebra equations also. Sometimes the quadratic equation becomes so difficult or complicated to solve or understand that it is quite difficult to solve them. For this, various quadratic equation solver are available over the internet. We can solve equations online by just putting our equation in equation solver. It provides us each step to solve an equation through which we can understand it in a better and faster manner.</p> </p><strong>About the Author:</strong><br /> <p>TutorVista is the #1 portal for learning <a rel="nofollow" href="http://math.tutorvista.com/algebra/solving-quadratic-equations-by-factoring.html" title="how to solve a quadratic equation">how to solve a quadratic equation</a> online.
