Question

what is discriminant? in mathematics.....​

Answer 1

Answer:

∆=b^2-4ac

ax^2+bx+c

are the value of a b and c

Step-by-step explanation:

the value of discriminate decides whether the roots of quadratic equation are real ,equal or unequal if the valu of discriminate is positive then the roots is real and unequal if 0 then the root is real and equal if the discriminate is in negative then the roots is not real and Equal

Answer 2

Answer:

A discriminant is a parameter of an object or system calculated as help to its classification or solution. In the case of a quadratic equation ax² + bx + c = 0, the discriminant is b² − 4ac;

For a cubic equation x³ + ax² + bx + c = 0, the discriminant is a²b² + 18abc − 4b³ − 4a³c − 27c².

The roots of a quadratic or cubic equation with real coefficients are real and distinct if the discriminant is positive, are real with at least two equal if the discriminant is zero, and include a conjugate pair of complex roots if the discriminant is negative.

A discriminant can be found for the general quadratic, or conic, equation ax²+ bxy + cy² + dx + ey + f = 0; it indicates whether the conic represented is an ellipse, a hyperbola, or a parabola.
