1.	If ∣∣∣∣a−b−c2a2a2bb−c−a2b2c2cc−a−b∣∣∣∣=(a+b+c)(x+a+b+c)2, x≠0 and a+b+c≠0, then x is equal to :
Answer» If $∣ ∣∣ ∣ \begin{matrix} a - b - c & 2 a & 2 a 2 b & b - c - a & 2 b 2 c & 2 c & c - a - b \end{matrix} ∣ ∣∣ ∣$ $= (a + b + c) (x + a + b + c)^{2}, x \neq 0$ and $a + b + c \neq 0$ , then $x$ is equal to :
