A second order nonlinear ordinary differential equation

If you are allowed to guess, then try guess a very often used function that when differentiated gives a scaled version of itself, i.e. a function that satisfy x' = a x, with a being a constant.
I've tried that but is there a way to actually solve it without guessing?
