To find: values of a and b

Formula used:

A square matrix A is said to be symmetric if aij = aji for all i and j or the transpose of matrix A is equal to matrix A itself, i.e. AT = A

a12 = a21 and a13 = a31

Here, a12 = 2b, a21 = 3, a13 = -2 and a31 = 3a

2b = 3 and 3a = -2 Hence, the values of a and b are and Rate this question :
