What is the complex conjugate?

The complex conjugate of a complex number is a number for which the real part is the same and for which the imaginary part has the same magnitude but opposite sign. e.g. the complex conjugate of 6+7i is 6-7i. It should be noted for a polynomial with real coefficients that complex roots come in complex pairs. So if the complex number is a root, its conjugate will be as well.

What is the value of x from (x+2)^2=4


The ODE mx'' + cx' + kx = 0 is used to model a damped mass-spring system, where m is the mass, c is the damping constant and k is the spring constant. Describe and explain the behaviour of the system for the cases: (a) c^2>4mk; (b) c^2=4mk; (c) c^2<4mk.
