Chapter 6.3, Problem 2E

u_{1 =} $\left[\begin{array}{c}1\\ 2\\ 1\\ 1\end{array}\right]$, u_{2 =} $\left[\begin{array}{c}-2\\ 1\\ -1\\ 1\end{array}\right]$, u_{3 =} $\left[\begin{array}{c}1\\ 1\\ -2\\ -1\end{array}\right]$, u_{4 =} $\left[\begin{array}{c}-1\\ 1\\ 1\\ -2\end{array}\right]$, v = $\left[\begin{array}{c}4\\ 5\\ -3\\ 3\end{array}\right]$

Write v as the sum of two vectors, one in Span {u₁} and the other in Span {u₂, u₃, u₄}.
