SUMMARY

The discussion focuses on the application of Laplace transforms in solving algebraic equations, specifically addressing the factorization of the term (kp)/(kp-1). The user seeks clarification on the partial fractions decomposition method, rewriting the expression as k_p(A/s + B/(s - 1 + k_p)). The goal is to determine the constants A and B to establish the identity. This method is essential for simplifying complex algebraic expressions in control systems and differential equations.

I put this in this forum because its actually a laplace transform question

basically, I just can't see how he is factoring out (kp)/(kp-1)
any ideas?

It looks to me like a partial fractions decomposition, rewriting
[tex]\frac{k_p}{s(s - 1 + k_p)}~=~k_p\left(\frac{A}{s} + \frac{B}{s - 1 + k_p}\right)[/tex]

The idea is to solve for A and B so that this equation is an identity.
