In algebra, a quadratic equation is any polynomial equation of the second degree with the following form: ax 2 + bx + c = 0. where x is an unknown, a is referred to as the quadratic coefficient, b the linear coefficient, and c the constant. The Discriminant And Three Cases Notice how in the quadratic formula there is a square root part after the plus and minus sign ($$\pm$$).The part inside the square root ($$b^2 - 4ac$$) is called the discriminant.An important property of square roots is that square roots take on numbers which are at least 0 (non-negative). These two roots are calculated once by putting the positive sign and another one by putting a negative sign. 3. c = 0. Quadratic Formula. A solution can either be real, or complex depending on the value of the discriminant. The calculator works the entered math problem using the quadratic formula. Now store b so type 5 .
