If a, b, c are real numbers, the polynomial has two distinct real roots if the discriminant is positive, and two complex conjugate roots if it is negative.

The discriminant formula is used to find the number of solutions that a quadratic equation has. In algebra, the discriminant is the name given to the expression that appears under the square root (radical) sign in the quadratic formula.

Discriminants also are defined for elliptic curves and other mathematical entities.

Diskriminanta formula

Kvadratna funkcija Kvadratna funkcija je funkcija, ki jo lahko zapišemo z enačbo oblike f (x) = ax 2 + bx + c, kjer so koeficienti a, b in c poljubna realna števila in je vodilni koeficient a različen od 0. Enačbo oblike f (x) = ax 2 + bx + c imenujemo splošna oblika enačbe kvadratne funkcije. Vsako kvadratno funkcijo lahko zapišemo tudi v temenski obliki: f (x) = a(x − p) 2 + q.

In the case of a quadratic equation ax 2 + bx + c = 0, the discriminant is b 2 − 4ac; for a cubic equation x 3 + ax 2 + bx + c = 0, the discriminant is a 2 b 2 + 18abc − 4b 3 − 4a 3 c − 27c 2.

Diskriminanta formula

In the case of a quadratic equation ax 2 + bx + c = 0, the discriminant is b 2 − 4ac; for a cubic equation x 3 + ax 2 + bx + c = 0, the discriminant is a 2 b 2 + 18abc − 4b 3 − 4a 3 c − 27c 2. The reason that the number of solutions depends on discriminant will be more clear in next lesson, Quadratic Formula. In short, the discriminant is a part of the Quadratic Formula. Mathematically, using a square root as a part of the formula results in a different number of solutions depending on the sign of the radicand (number under the The discriminant of a quadratic formula is the part of the quadratic formula that determines the root type in a quadratic equation (imaginary, real, singular).

The discriminant tells us whether there are two solutions, one solution, or no solutions. The discriminant for any quadratic equation of the form $$ y =\red a x^2 + \blue bx + \color {green} c $$ is found by the following formula and it provides critical information regarding the nature of the roots/solutions of any quadratic equation. Дискриминантата е тази част от формулата за намиране на корените на квадратно уравнение, която се намира под знака за квадратен корен: b²-4ac.
