Aside from delicious pi, have you tried just writing the equation of a cubic polynomial down and then doing your operations using normal algebra?Pi.

Cool problem. Thanks.

I'm trying to rewrite the cubic formula (the general solution for the roots of a cubic polynomial into the form (3ax +b)^3 = ...

Where normally given a cubic polynomial equation

ax^3 + bx^2 + cx + d = 0

The answer can be found by making the substitution:

a = b/a

b = c/a

c = d/a

and then the formula is in this link:
