Mass m attached to spring with spring constant k=Am. It feels a resistive force magnitude Bmv where v is the speed. and A, B are constants such that 4A > B^2

What is the fractional change in amplitude of oscillation in one complete oscillation?

2. Relevant equations

3. The attempt at a solution

Ok so ive written down the DE:

x'' + Bx' - Ax = 0 and solved..but this gives be Ce^-Lt + De^-L't where C, D, L and L' are constants...

1) i dont see how this oscillates... 2) how do i work out fractional change in amplitude of oscillation?
