The Quadratic Formula Calculator finds solutions to quadratic equations with real coefficients. If you choose to write your mathematical statements, here is a list of acceptable math symbols and operators. Enter the equation you want to solve using the quadratic formula. Solving quadratic equations by factoring Quadratic equations by completing the square Series and Progressions. Available as a mobile and desktop website as well as native iOS and Android. With the calculator, you can practice on how to find the roots of a quadratic equation simply by working the problem your own way and comparing the results with those of the calculator. Free Algebra Solver and Algebra Calculator showing step by step solutions. This calculator not only gives you the answers but it helps you learn algebra too. Here are more examples to help you master the factoring equation method. The calculator factors nicely with all the steps. Using this calculator enables you to factor a quadratic equation accurately and efficiently. You can factor polynomials of degree 2 in order to find its solution. Step 3: Equate Each of the product to Zero Step 2: Choose best combination for Factoring, Then Factor And Simplify Step 1: Find j=-6 and k=1 Such That j*k=-6 And j+k=-5 To illustrate how the factoring calculator works step by step, we use an example.
An algebra calculator that finds the roots to a quadratic equation of the form ax^2+ bx + c = 0 for x, where a \ne 0 through the factoring method.Īs the name suggests the method reduces a second degree polynomial ax^2+ bx + c = 0 into a product of simple first degree equations as illustrated in the following example:Īx^2+ bx + c = (x+h)(x+k)=0, where h, k are constants.įrom the above example, it is easy to solve for x, simply by equating either of the factors to zero. The solution (s) to a quadratic equation can be calculated using the Quadratic Formula: The '±' means we need to do a plus AND a minus, so there are normally TWO solutions The blue part ( b2 - 4ac) is called the 'discriminant', because it can 'discriminate' between the possible types of answer: when it is negative we get complex solutions.
