Question

the discriminant of quadratic equation ax²+bx+c=0​

Answer 1

Answer:

a²b² + 18abc − 4b³ − 4a³c − 27c².

Step-by-step explanation:

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.
