If a,b,c are the roots of the equation x3−4x+24=0, then the equation who’s roots are b+c,c+a and a+b is given by?
a+b+c=0 ( coefficient of x2 is 0) therefore
b+c=-a, a+b=-c, and a+c=-b
The equation who’s roots are –a,-b and –c is obtained by replacing x by –x in the equation
The required equation is (−x)3−4(−x)+24=x3−4x−24=0.
