But manually, it is not very easy to find the roots of an equation. The quadratic formula is the simplest way to solve these 2nd order equations. In algebra, quadratic equations are important to solve because the roots of the equations tell the solution's nature. Why to use Quadratic Formula Calculator with Variables? You will get the result a few seconds after you click on the calculate button. Click on the “Calculate” button to start the computation.Now enter the value of c in the “Enter the value of (c)” box.Now enter the value of b in the “Enter the value of (b)” box.Enter the value of an in the “Enter the value of (a).” You need to enter the values of the polynomial constants as an input.There are some simple steps to use this tool online that can easily find the roots of an equation whose polynomial degree is 2. How to use Quadratic Equation Solver with steps? Hence this tool does not only solve the equation to find its roots but also explains the nature of the roots. If b 2-4ac=0, the roots of the equation are real and equal.If b 2-4acIf b 2-4ac>0, the roots of the equation will be real and distinct.It also tells the nature of the roots by using these conditions: The quadratic calculator uses this formula to find the roots of the given polynomial. Where a, b and c are the constants of the polynomial. This equation can be solved by using quadratic formula which is: The quadratic equation is a second degree polynomial in which the highest power of an independent variable is 2. Formula used by Quadratic Equation Calculator But manual computation includes more than one step we introduce a tool that can solve the equation in a single step. We put the values of constants in the quadratic formula and find the roots of the equation. We prefer to use it instead of using the method of factorization. The quadratic formula is an important concept for solving any quadratic equations in algebra. It uses the quadratic formula to compute the values for an independent variable, 'x.' It finds' x' values for an equation with degree 2. It's shape is a parabola, and the roots of the quadratic equation are the x-intercepts of this function.Introduction to Quadratic Formula CalculatorĪ quadratic calculator is an online tool used to evaluate any quadratic equation. You can also graph the function y = Ax² + Bx + C. The quadratic equation has no real solutions for Δ < 0. It is sometimes called a repeated or double root. The quadratic equation has only one root when Δ = 0. Then, the first solution of the quadratic formula is x₁ = (-B + √Δ)/2A, and the second is x₂ = (-B – √Δ)/2A. The quadratic equation has two unique roots when Δ > 0. Note that there are three possible options for obtaining a result: Using this formula, you can find the solutions to any quadratic equation. A solution to this equation is also called a root of an equation. If you can rewrite your equation in this form, it means that it can be solved with the quadratic formula. The quadratic formula is the solution of a second-degree polynomial equation of the following form:
