Solve quadratic equations using a quadratic formula calculator. Calculator solution will show work for real and complex roots. Uses the quadratic formula to solve a second-order polynomial equation or quadratic equation.
A root is a value for which the function equals zero. The roots are the points where the function intercept with the x-axis. Complex roots are the imaginary roots of a function. To find the complex roots of a quadratic equation use the formula: x = (-b±i√ (4ac – b2))/2a.
A useful tool for finding the solutions to quadratic equations. Wolfram|Alpha can apply the quadratic formula to solve equations coercible into the form ax 2 + bx + c = 0. In doing so, Wolfram|Alpha finds both the real and complex roots of these equations. It can also utilize other methods helpful to solving quadratic equations, such as ...
