Welcome to Quadratic-Equation-Calculator.com, a free quadratic equation solver and tutorial.
A quadratic equation is any equation of the form ax2+bx+c=0, where a, b, and c are constants, and x is an unknown. Note that if a=0, the equation becomes bx+c=0, which is a linear equation, not a quadratic equation.
To solve your quadratic equation, and to get a step-by-step explanation of how that solution is reached, type your values for a, b, and c in the boxes above.
