A2+b2+c2 Ab Bc Ca

Here we will express a^2 b^2 c^2 – ab – bc – ca as sum of squares If a, b, c are real numbers then (a – b)^2, (b – c)^2 and (c – a)^2 are positive as square of every real number is positive So, a^2 b^2 c^2 – ab – bc – ca is always positive.

A2+b2+c2 ab bc ca. If a^2b^2c^2abbcca=0 then prove that a=b=c a² b² c² = ab bc ca On multiplying both sides by “2”, it becomes 2 (a² b² c²) = 2 (ab bc ca). (a b) 2 This can also be written as = (a b) (a b) Multiply as we do multiplication of two binomials and we get = a(a b) b(a b) = a 2 ab ab b 2 Add like terms and we get = a 2 2ab b 2 Rearrange the terms and we get = a 2 b 2 2ab Hence, in this way we obtain the identity ie (a b) 2 = a 2 b 2 2ab.
