Consider the block diagram in Figure 4.26. Use the block-diagram reduction steps listed in the following to find \(Y(s) / U(s)\).

a. Replace the single loop containing \(G_{1}(s)\) and \(H(s)\) with a single equivalent block.

b. Move the gain block \(K\) to the right of the summing junction.

c. Replace the resulting loop with a single equivalent block.
