Whether your equation has real or complex roots, our tool delivers the correct solution. Our calculator is equipped with advanced algorithms that ensure the results are accurate every time. Why Choose Our Quadratic Equation Calculator? If $$$b^2-4ac\lt0 $$$, the equation has two complex roots. Question 5: What is the formula for solving quadratic equation Answer: The general quadratic equation formula is ax2 + bx + c.If $$$b^2-4ac=0 $$$, there's one real root (a repeated root).To deal with that we divide the whole equation by 'a' first, then carry on: x 2 + (b/a)x + c/a. But a general Quadratic Equation may have a coefficient of a in front of x 2: ax 2 + bx + c 0. We can complete the square to solve a Quadratic Equation (find where it is equal to zero). If $$$b^2-4ac\gt0 $$$, the equation has two distinct real roots. Solving General Quadratic Equations by Completing the Square.The term inside the square root is called the discriminant. The quadratic formula is a universal method to find the roots or solutions of any quadratic equation. Depending on the values of $$$a $$$, $$$b $$$, and $$$c $$$, the parabola can open upwards or downwards and have its vertex anywhere in the coordinate plane. Quadratic Equations are used in real-world applications. The graphical representation of a quadratic function is a parabola. A quadratic equation is a second-order equation written as ax 2 + bx + c 0 where a, b, and c are coefficients of real numbers and a 0. It's essential that $$$a\ne0 $$$, otherwise, the equation will not be quadratic but linear.$$$x $$$ is the variable or the unknown we aim to find. Solve Quadratic Equations Using the Quadratic Formula Write the quadratic equation in standard form, ax2 + bx + c 0.It has the following form: $$ax^2+bx+c=0, $$ A quadratic equation can have one of three types of roots: two distinct real roots, one repeated real root, or two complex roots.Ī quadratic equation is a particular type of polynomial equation of the second degree. In a short moment, the calculator will show the roots. The calculator will quickly determine the solutions of the equation. How to Use the Quadratic Equation Calculator?Įnter the given quadratic equation and choose the method for solving it.Īfter entering the equation, click the "Calculate" button.
