Question

If the centroid of a triangle formed by the points A [ a, b ] ,  B [ b , c ] , C [ c , a ] is at the origin , then what is the value of a^2/bc+b^2/ca+c^2/ab ???????????????????????

Answer 1

We for centroid:-
(a+b+c/3,b+c+a/3) = (0,0)
a+b+c=0..i    b+c+a=0.......iii
Then follow subsitution method and yoy are done
