![]() Our calculator provides immediate solutions, allowing users to quickly move on to other tasks or verify their manual calculations without delay. We've developed a simple and intuitive interface that even those new to quadratic equations can easily navigate. Use the formula to solve theQuadratic Equation: y x2 + 2x + 1 y x 2 + 2 x + 1. Step 2: Find (1 2 b)2, the number to complete the square. This equation has all the variables on the left. Solution: Step 1: Isolate the variable terms on one side and the constant terms on the other. Whether your equation has real or complex roots, our tool delivers the correct solution. Solve by completing the square: x2 + 8x 48. 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.If $$$b^2-4ac=0 $$$, there's one real root (a repeated root). ![]() If $$$b^2-4ac\gt0 $$$, the equation has two distinct real roots.This is enough to start sketching the graph. It also reveals whether the parabola opens up or down. The term inside the square root is called the discriminant. This form reveals the vertex, ( h, k), which in our case is ( 5, 4). The quadratic formula is a universal method to find the roots or solutions of any quadratic equation. ![]() Solving quadratic equations is no modern accomplishment. 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. History of the Quadratic Formula Early History. The graphical representation of a quadratic function is a parabola.
