In Example 7, change the denominator of the third fraction to s2 + 4s and then find the result.
Data from Example 7
The following expression is found in the analysis of the dynamics of missile firing. The indicated addition is performed as shown.
We factored the numerator in the final result to see whether or not there were any factors common to the numerator and the denominator. Because there are none, either form of the result is acceptable.
= -+ = 1/2 1__1 8 S S 4 s2 + 8s + 16 S = = = 1 S+ 4 + 1(s+4)-1(s) (s + 4) + 8s s(s+4) 12s + 16 s(s+ 4) 8 (s + 4) s +8s + 16 - $ s(s+4) + 4s +8s 4(3s + 4) s(s+4)
