- Discriminant - Formula, Rules, Discriminant of Quadratic Qquation - Cuemath
The discriminant is widely used in the case of quadratic equations and is used to find the nature of the roots Though finding a discriminant for any polynomial is not so easy, there are formulas to find the discriminant of quadratic and cubic equations that make our work easier
- A Complete Guide to the Discriminant of Quadratic
To calculate the discriminant of a quadratic equation, the formula is b2 – 4ac Substitute the values of a, b and c after reading them from a quadratic equation of the form a𝑥2 + b𝑥 + c For example, for 𝑥2 – 3𝑥 + 4, a = 1, b = -3 and c = 4 b2 = 9 and 4ac = 16 The discriminant, b2 – 4ac = – 7
- Discriminant | Definition, Examples, Facts | Britannica
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 discriminant is b^2 - 4ac Discriminants also are defined for elliptic curves and other mathematical entities

- Discriminant Definition in Math - BYJUS
The discriminant of a quadratic polynomial is the portion of the quadratic formula under the square root symbol: b 2-4ac, that tells whether there are two solutions, one solution, or no solutions to the given equation
- The Discriminant | Intermediate Algebra - Lumen Learning
The discriminant of the quadratic formula is the quantity under the radical, [latex]{{b}^{2}}-4ac[ latex] It determines the number and the type of solutions that a quadratic equation has If the discriminant is positive, there are [latex]2[ latex] real solutions
- Discriminant in Maths: Formula, Meaning Root Analysis - Vedantu
The name "discriminant" comes from the fact that it distinguishes between the equation's solutions (as equal and unequal; real and nonreal) It is commonly denoted by Δ or D The discriminant's value can be any real number (i e , either positive, negative, or 0)
- Understanding the Discriminant in Quadratic Equations
The discriminant is a key component of the quadratic formula that determines the nature and number of solutions to a quadratic equation In the standard form ax² + bx + c = 0, the discriminant is represented by the expression b² - 4ac
