Question

a+b+c=2s; (s-a)^3+ (s-b)^3 + 3(S-a)
(s-b)c =?​

Answer 1

Answer:

Given (s-a)3 + (s-b)3 + 3c(s-a)(s-b)

⇒ (s-a) 3 + (s-b) 3 + 3(2s-a-b)(s-a)(s-b)

⇒ (s - a)3 + (s - b)3 + 3(s - a + s - b)(s - a)(s - b)

let x = (s - a), y = (s - b)

(x + y)3 = x3 + y3 + 3 (x + y) xy

⇒ (s - a + s - b)3

⇒ (2s- a - b)3

= c3 .
