In mathematics, the discriminant of a polynomial is a quantity that depends on the coefficients and allows deducing some properties of the roots without computing them. More precisely, it is a …

The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.

To find the discriminant of a cubic equation or a quadratic equation, we just have to compare the given equation with its standard form and determine the coefficients first. Then we substitute …

The discriminant is the part of the quadratic formula found within the square root. For a quadratic of the form a𝑥2 + b𝑥 + c, its discriminant is b2 – 4ac.

Discriminant, in mathematics, a parameter of an object or system calculated as an aid to its classification or solution. In the case of a quadratic equation, ax^2 + bx + c = 0, the …

In mathematics, the discriminant is a specific part of the quadratic formula used to analyse a quadratic equation of the form ax² + bx + c = 0. It is the expression found under the square …

Illustrated definition of Discriminant: The expression b2 minus; 4ac used when solving Quadratic Equations. It can discriminate between...
