If alpha , beta , gamma, are the roots of the equation :-
a x3 +b x2 +c x + d = 0 then what is the equation whose roots are :-
alpha - ( 1 / beta.gamma) , beta- ( 1 / alpha.gamma) , gamma( 1 / beta.alpha) ?

from given eqn, consider l,m,n such dat they r reciprocals of abv 3 lmn = (    ) 2 / ( - 1) 3 = -ad 2 / (a+d) 3eqn whose roots r l,m,n is (a+d)3x3 + (a+d)2cx2 - bd(a+d)x + ad2 = 0 to obtain req, eqn change x 2 1/x ad2x3 - bd(a+d)x2 + (a+d)2cx + (a+d)3 = 0
