Question

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

Answer 1

Answer:

I think the question is not complete. I will solve this question by assuming the two roots are equal.

Step-by-step explanation:

If two roots of this equation are equall then D=(b-c)^2-4(a-b)(c-a)=0;

or,{(a-b)+(c-a)}^2-4(a-b)(c-a)=0;

or, {(a-b)-(c-a)}^2=0;
