If alpha and beta are roots of ax^(2)+bx+c=0 ,and roots differ by k then b^(2)-4ac=

If 'alpha and beta are roots of ax^(2)+bx+c=0 ,and roots differ by k then b^(2)-4ac=

If one root of the equation ax^2+bx+c=0 be the square of the other and b^3+a^2c+ac^2=kabc then k=

If the roots of the equation ax^(2)+bx+c=0 are of the form (k+1)/k and (k+2)/(k+1), then (a+b+c)^(2) is equal to 2b^(2)-ac b.a62 c.b^(2)-4ac d.b^(2)-2ac

If one root of the equation ax^2+bx+c=0 be the square of the other,and b^3+a^(2)c+ac^2=k abc,then the value of k

If one root of the equation ax^(2)+bx+c=0 be the square of the other, and b^(3)+a^(2) c+ac^(2)=kabc , then the value of k is
