yes. there is a formula first u put x=y-b/3a then substitute in the cubic equation then you get the equation which do not have x2 term
that is a cubic in x with co-efficient of x2=0 then if u get a cubic like this, y3+ay=b,put b=s3-t3&a=3st(assumption) then,u observe that,y=s-t satisfies y3+ay=b hence s=a/3t solve for t then solve for s hence u can get y from that,u can get x hence cubic equation is solved please rate me
