Solving a cubic equation: Cardan's method

[@freddyalvaradamaranon304]

Muy interesante video, muchas gracias por compartir 😊. No conocía el método de Cardan para resolver ecuaciones de tercer grado. 😊❤😊.

27=2×9,54=9×6
6(6^2-27-9)=0
x+6 is a factor of lhs
lhs=(x+6)(x^2+6x+9)=0=rhs
x=6 or -3,-3

I couldn't solve it because i had to find out the cube root of -4+4isqrt(3). Which I don't know how.
