Resolution of a generic cubic

Algebra Level pending

for a generic equation ( a ( x 3 ) ) + ( b ( x 2 ) ) + ( c x ) + d = 0 (a(x^3))+(b(x^2))+(cx)+d=0 .... then ( x 3 ) − ( 3 ( x 2 ) ) + 3 x − 1 = 0 (x^3)-(3(x^2))+3x-1=0 has solution ....

There are 2 ways.... the first ( x + a ) 3 = x 3 + 3 x 2 a + 3 x a 2 + a 3 = 0 (x+a)^3=x^3+3x^2a+3xa^2+a^3=0 then for comparison you obtain the aswer... the second is by this metod
