Question 14571
Help me please!
I don't understand what I am suppose to do.

Evaluate the determinant of the matrix.

items in a bracket.  3   -2   0
                     -1   5   3
                     2    7   1

The determinant of matrix 
 {{{(matrix(3,3,3,-2,0,-1,5,3,2,7,1))}}}

is evaluated in the usual manner as that of a determinant.IF IT IS NOT KNOWN TO YOU IT CAN BE EXPLAINED ON HEARING FROM YOU>
taking any one column  or row .Expanding by using the first column of 3,-1,2 we get the value of the determinant as
=3*(5*1-3*7)-(-1)*((-2)*1-0*7)+2*((-2)*3-0*5)
=-48-2-12=-62
