a) Solve the inconsistent system Ax=b given by 1 10 1 0

a) Solve the inconsistent system Ax=b given by 1 10 1 0 1 C Z 1-[21 = using the method of least squares. (As A A is not invertible, there will be infinitely many solutions.) b) Give two least-squares solutions X and X2. c) The error for a least-squares solution x is Axb||. Verify that the least-squares error is the same for both your solutions X and X.
