I wrote x² - (a + b)x + (ab) in the wolfram and polynomial discriminant was: a² - 2ab + b². Factoring: (a-b)²
---
So, I wrote x³ - (a+b+c) x² + (bc+ca+ab) x - (abc) and the polynomial discrimant given was:
Factoring: (b-c)² (c-a)² (a-b)²
---
Now, I wrote x² - 2Ax + B² and the polynomial discriminant is: A² - B². Factoring: (A+B)(A-B)
---
At last, but, no minus important, given this polynomial: x³ - 3 A x² + 3 B² x - C³, which is the factored form of the polynomial discriminant?
