If a,b,c are non negative real numbers and ∣∣∣∣∣(a2+x2)abaca – InterviewSolution

1.	If a,b,c are non negative real numbers and ∣∣∣∣∣(a2+x2)abacab(b2+x2)bcacbc(c2+x2)∣∣∣∣∣ is divisible by xn, where n∈N, then the maximum possible value of n is
Answer» If $a, b, c$ are non negative real numbers and $∣ ∣∣∣ ∣ \begin{matrix} (a^{2} + x^{2}) & a b & a c a b & (b^{2} + x^{2}) & b c a c & b c & (c^{2} + x^{2}) \end{matrix} ∣ ∣∣∣ ∣$ is divisible by $x^{n}$ , where $n \in N$ , then the maximum possible value of $n$ is
