Answer:
Step-by-step explanation:
You already have the bottom in factors, write the partial fraction in the form As+b for each factor
Multiply both sides by the bottom to stop using fractions:
To find the value of the constants A, B, C, and D, separate the equation by the grade of the s, for example, all that multiplies s^3 in one equation like this:
Because in the left part of the equation doesn't have constants multiplying the s^3 we put a zero in that side of the equation, do the same with s^2,s^1, and s^0
In this case, you can group the equation by constant to solve. First A and D, then B and C.
Solving for A and C:
This system only has one solution A=0 and C=0.
Solving for B and D:
Then the solution is:
