Write x as the sum of two vectors, one in Span {u 1 , u 2 , u 3 }, and one in Span {u 1 ,.,u 4 } is an orthogonal basis for R 4 .

Write x as the sum of two vectors, one in Span {u1, u2, u3}, and one in Span {u1,...,u4} is an orthogonal basis for R4.

 U1= [0], u2=[5], u3=[1], u4=[7] ,x= [14]

       [1]         [7]        [0]       [-5]      [-9]

       [-6]       [1]        [1]       [-1]     [4]

      [-1]        [1]        [-6]     [1]       [0]

X=         (integer or simplified fraction for each matrix element.)
