Value of (a–c)[(a–b) 2 +(b–c) 2 –(a–b)(b–c)]+(c–a) 3 is equal to (1) 3(a – b) (b – c) (c –a) (2) (a – b) (b – c) (c – a) (3)(a–b) 3 (b–c) 3 (c–a) 3 (4)None of these
Solution={(a-b)+(b-c) }{(a - b)^2 + (b - c)^2 - (a - b) (b - c)} + (c - a)^3(x+y) (x^2 - xy+y^2) =x^3 + y^3=(a-b)^3 +(b-c)^3 +(a-c) ^3On solving it further=0
Solution
={(a-b)+(b-c) }{(a - b)^2 + (b - c)^2 - (a - b) (b - c)} + (c - a)^3
(x+y) (x^2 - xy+y^2) =x^3 + y^3
=(a-b)^3 +(b-c)^3 +(a-c) ^3
On solving it further
