It is highly unlike that we need to utilise the General Solution of Cubic equations anytime soon, as its completely out of the syllabus, and creates more working compared to other methods.

however, there is a interesting method here which solves cubic equations if coefficient before x2 is zero.

Let

x3 + 3ax = 2b

be the general cubic equation.

Let x = a/y - y

Hence equation becomes:

y6 + 2by3 - a3 = 0

which is a quadratic equation in y3; solve for y3, extract the cube root y; and compute the x- values

Can this method be used legally for ext2.
