The Value of Discriminant Calculator is a vital tool in quadratic equations, assisting in understanding the nature of solutions. It calculates the discriminant (Δ) using a simple formula:
Δ = b^2 – 4ac
Here, Δ (Delta) represents the discriminant, while ‘a’, ‘b’, and ‘c’ denote the coefficients of the quadratic equation. The resulting value of Δ governs the nature of the solutions:
- Δ > 0: Indicates two distinct real solutions (two different real roots).
- Δ = 0: Represents a singular real solution (a repeated real root).
- Δ < 0: Implies no real solutions (complex conjugate roots).
This calculator provides a quick insight into the possible outcomes of a quadratic equation, guiding users through the solution process efficiently.

Example of Value of Discriminant Calculator
Consider the quadratic equation: 2x^2 + 5x – 3 = 0
By applying the discriminant formula (Δ = b^2 – 4ac) where ‘a’ is 2, ‘b’ is 5, and ‘c’ is -3, we can determine the nature of its roots:
Δ = (5)^2 – 4 * 2 * (-3)
Δ = 25 + 24
Δ = 49
Given Δ > 0, this equation has two distinct real solutions.
