I need help multiplying out the following expression:
C(Z) =
0.1(Z+0.5)
----------------------
(Z-1)(Z-0.2)
----------------------------------------…
1 + 0.1(Z+0.5) x 0.2Z
------------------ -----------
( Z-1)(Z-0.2) (Z-0.8)
After I have multiplied out this expression I am supposed to do the equation:
E(Z) = 1- C(Z)
The correct answer for E(Z) on the problem sheet is:
Z^3 - 2.08^Z2 + 1.2Z - 0.12
--------------------------------------
Z^3 - 1.98Z^2 + 1.17Z - 0.16
Could someone show me the step by step for this question so I know how to answer the rest of them. Thanks
