If a + b + c = -11, then what is the value of (a + 4)3 + (b + 5)3 + (c + 2)3 - 3(a + 4)(b + 5)(c + 2)?
A. -1331
B. -121
C. 0
D. 1331
Answer: Option C
Solution (By Examveda Team)
Given,a + b + c = -11
By putting value i.e.
a = -4
b = -5
c = -2
Therefore,
(a + 4)3 + (b + 5)3 + (c + 2)3 - 3(a + 4)(b + 5)(c + 2)
= 0 + 0 + 0 - 0
= 0
