1.	Let A=[23a0], a∈R be written as P+Q where P is a symmetric matrix and Q is skew symmetric matrix. If det(Q)=9, then the modulus of the sum of all possible values of determinant of P is equal to
Answer» Let $A = [\begin{matrix} 2 & 3 a & 0 \end{matrix}],$ $a \in R$ be written as $P + Q$ where $P$ is a symmetric matrix and $Q$ is skew symmetric matrix. If $det (Q) = 9,$ then the modulus of the sum of all possible values of determinant of $P$ is equal to
