Multiply both sides with 2, we get. 2(a2 + b2 + c2ab-bc-ca) = 0. → 2a2 + 2b2 +2c2 - 2ab - 2bc - 2ca = → a2 + a2 + b2 + b2 + c2 + c2- 2ab - 2bc2ca0 (a2 - 2ab + b2) + (b2-2bc + c2) + (c2 - 2ca + a2) = 0 (a - b)2 + (b − c)2 + (ca)2 = 0. Since the sum of squares is zero, it means each term should be zero. WebSolution Verified by Toppr Correct option is A) L.H.S.=2a 2+2b 2+2c 2−2ab−2bc−2ca On re-arranging the terms, we get =(a 2−2ab+b 2)+(b 2−2bc+c 2)+(c 2−2ca+a 2) =(a−b) …
