Quadratic formula

For the Quadratic Formula to work, you must have your equation arranged in the form (quadratic) = 0.Also, the 2a in the denominator of the Formula is underneath everything above, not just the square root.And it's a 2a under there, not just a plain 2.Make sure that you are careful not to drop the square root or the plus/minus in the middle of your calculations, or I can guarantee that. In the quadratic formula, the expression underneath the square root sign is called the discriminant of the quadratic equation, and is often represented using an upper case D or an upper case Greek delta: = −. A quadratic equation with real coefficients can have either one or two distinct real roots, or two distinct complex roots. In this case the discriminant determines the number and nature. Shows you the step-by-step solutions using the quadratic formula! This calculator will solve your problems
