If `a (b - c) x^2 + b (c-a) x + c (a - b) = 0` has equal root, then `a, b, c` are in

If the roots of the equation : (b-c)x^(2) + (c-a) x + ( a-b) = 0 are equal, then a,b,c are in :

IF the roots of a(b-c)x^2+b (c-a) x+c (a-b) =0 are equal then a, b, c are in

If the equation a(b - c)x^2 + b(c - a)x+c (a -b) = 0 has equal roots, prove that 1/a+1/c=2/b

Let a(b - c)x^2 + b(c - a)x + c(a -b) = 0 has two equal roots. The true relation is _____

If the roots of the equation a(b-c)x^(2) + b(c-a) x+c(a-b)=0 are equal, then prove that a, b, c are in H.P

IF the roots of (b-c) x^2+ (c-a) x+ (a-b) =0 are equal then a, b,c are in
