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 …

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, b 2 – 4ac is represented by the delta symbol, Δ. The discriminant formula is Δ = b 2 – 4ac, where a is the coefficient of 𝑥 2, b is the coefficient of 𝑥 and c is the constant term of a …

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 …

For a x 2 + b x + c = 0, where a, b, and c are real numbers, the discriminant is the expression under the radical in the quadratic formula: b 2 4 a c. It tells us whether the solutions are real …

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 …

What is the discriminant anyway? Answer The discriminant is a number that can be calculated from any quadratic equation. A quadratic equation is an equation that can be written as $$ …
