MCQ (Single Correct Answer)

-0.3

The open loop transfer function of a unity feedback open-loop system is $$\frac{2s^2+6s+5}{\left(s+1\right)^2\left(s+2\right)}$$. The characteristic equation of the closed loop system is

$$2s^2+6s+5=0$$

$$\left(s+1\right)^2\left(s+2\right)=0$$

$$2s^2+6s+5+\left(s+1\right)^2\left(s+2\right)=0$$

$$2s^2+6s+5-\left(s+1\right)^2\left(s+2\right)=0$$
