First write the given homogeneous system in the matrix form Ax = 0. Then find the solution in vector form. - 5X3 + 6X4 = 0 X2 + 3X3 - 2X4 = 0 . . . X1 X2 = X3 XA (Simplify your answers.) Find the solution in vector form. Select the correct choice below and, if necessary, fill in the answer box within your choice. O A. There are infinitely many solutions of the form x = sx1, where s is an arbitrary parameter and x, = O B. There is a unique solution, X = O C. There are infinitely many solutions of the form x = sx, + tx2, where s and t are arbitrary parameters and (x1,X2) = {}. (Use a comma to separate vectors as needed.) O D. There is no solution
