In case of a quadratic equation with a positive discriminate the roots are real while a 0 discriminate indicates a single real root.

Cool math snail bob 6 winter story. For example if the variable x stands for the movement of an object then dx means the change in movement scientists use this mathematical meaning of delta often in physics chemistry and engineering and it appears often in word problems. The 1976 formula is the first formula that related a measured color difference to a known set of cielab coordinates. A negative discriminant indicates imaginary complex number format roots.

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.
