If a + b + c = 0, then the value of (a + b – c)2+ (b + c – a)2+ (c + a – b)2is

If a + b + c = 0, then the value of (a + b – c)2+ (b + c – a)2+ (c

1.	If a + b + c = 0, then the value of (a + b – c)2+ (b + c – a)2+ (c + a – b)2is
A.	0
B.	8 abc
C.	4(a2+ b2+ c2)
D.	4(ab + bc + ca)
Answer» D. 4(ab + bc + ca)

If x = 2 then the value of x3 + 27x2 + 243x + 631 is:
If ab + bc + ca = 0, then the value of {1 / (a2 – bc)} +{1 / (b2 – ac)} +{1 / (c2 – ab)} is
If x + (1 / x) = 5, then {2x / (3x2 – 5x + 3)} is equal to
If x = 332, y = 333, z = 335 then the value of x3+ y3+ z3– 3xyz = ?
When 2x + (2 / x) = 3, then value of x3 + ( 1 / x3) + 2 is
If x = 6 + (1 / x), then the value of x4 + (1 / x4) is
If x2 – 3x + 1 = 0, then the value of (x6 + x4 + x2 +1) / x3 will be
If x3 + (3 / x) = 4(a3 + b3) and 3x + (1 / x3) = 4(a3 – b3), then a2 – b2 is equal to:
If x + (1 / x) = 5, then the value of x6 + (1 / x6) is
If x + y = 15, then (x – 10)3+ (y – 5)3is
