If two of the roots of `x^3 + ax + b=0` are equal then

If two roots of x ^(3) -ax ^(2) + bx -c =0 are equal in magnitude but opposite in sign. Then:

If two roots of x ^(3) -ax ^(2) + bx -c =0 are equal in magnitude but opposite in sign. Then:

If the difference between the roots of x^(2) + ax + b = 0 is equal to the difference between the roots of x^(2)+px+q= 0 then a^(2)-p^(2) =

If A.M of the roots of x^(2)-2ax+b^(2)=0 is equal to the ......... of the roots of the equation x^(2)-2bx+a^(2)=0

The non-trival values of (a,b) such that roots of the equation x^(2) + ax + b = 0 are equal to a and b are :

If one root of the equation x^(2)+Ax+12=0 is 4 and the roots of x^(2)+2Ax+B=0 are equal,then N value of B is

If the difference between the roots of x^2+ax+b=0 is equal to the difference between the roots of x^2+px+q=0 then a^2-p^2=

If the two roots of 9x^(3)+24x^(2)+13x+12x+2=0 are equal then the roots are
