Answer

a_{ji} $for all$ i, j$.

Step 1: Solve Question 1(a). For matrix $A$ to be symmetric, its transpose $A^T$ must be equal to $A$ . This means $a_{ij} = a_{ji}$ for all $i, j$ . The given matrix is $A = \begin{pmatrix} 9 & -6 & 2 \\ b & c & -2 \\ 9 & -2 & 4 \end{pmatrix}$ . The question asks to find $a, b, c$ . It is assumed that the element $a_{31}$ (which is currently 9) should be $a$ . So, let $A = \begin{pmatrix} 9 & -6 & 2 \ b & c & -2 \ a
