GATE CE 2017 Set 2

MCQ (Single Correct Answer)

-0.3

Consider the following simultaneous equations (with $${c_1}$$ and $${c_2}$$ being constants): $$$3{x_1} + 2{x_2} = {c_1}$$$ $$$4{x_1} + {x_2} = {c_2}$$$

The characteristic equation for these simultaneous equation is

$${\lambda ^2} - 4\lambda - 5 = 0$$

$${\lambda ^2} 4\lambda + 5 = 0$$

$${\lambda ^2} + 4\lambda - 5 = 0$$

$${\lambda ^2} + 4\lambda + 5 = 0$$
