For a system with the transfer function H(s) = 3(s

For a system with the transfer function H(s) = 3(s - 2) f, the matrix A
4s² - 2s + 1

in the state space form x = Ax + Bu is equal to

It is state space representation using phase variable.
Standard form
Thus ATQ a_n = 1, a_{n – 1} = – 2, a_{n – 2} = 4

For a system with the transfer function H(s) =	3(s - 2)	f, the matrix A
	4s² - 2s + 1
