If x2 = y + z, y2 = z + x and z2 = x + y, then the value of

A.
1
x2 = y + z, y2 = z + x, z2 = x + y
By hit and trial method,
Put the value of x = y = z = 2 as it satisfies the equation,
If a2 + b2 + 4c2 = 2(a + b - 2c) - 3 and a, b, c are real, then the value of (a2 + b2 + c2) is
2
3
If x ≠ 0, y ≠ 0 and z ≠ 0 and
, then the relation among x, y and z is
x = y = z
x + y + z = 0
x + y = z
If x2 + y2 + z2 = 2(x - y - z) - 3, then the value of 2x - 3y + 4z is (assume that x, y and z) are all real numbers).
