if the roots of the equation `a(b-c)x^2+b(c-a)x+c(a-b)=0` are equal then show that `2/b=1/a+1/c`

If the roots of the equation a(b-c)x^(2)+b(c-a)x+c(a-b)=0 are equal,show that 2/b=1/a+1/c.

The roots of the equation (b-c)x^(2)+(c-a)x+(a-b)=0

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

If the roots of the equation a(b-c)x^(2)+b(c-a)x+c(a-b)=0 are equal show that 1/a,1/b,1/c are in A.P.

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