Suppose the vectors {x}_{1}, {x}_{2} and {x}_{3} are the solutions of the system of linear equations, {Ax}= {b} when the vector {b} on the right side is equal to {b}_{1}, {b}_{2} and {b}_{3} respectively. If x_1=[\table 1;1;1],x_2=[\table 0;2;1], x_3=[\table0;0;1],b_1=[\table1;0;0] b_2=[\table0;2;0] and b_3=[\table 0;0;2], then the determinant of A is equal to :- [4 Sep 2020 Shift 2]
