when solving 2nd order DE, can we jump straight into the auxiliary equation or do we have to induce the auxiliary equation by firstly assuming the answer must be in a form of Ae^kx?

has the form of 
then the following steps of:
can all be skipped to just say the last line since at A-Level this is the only function you really work with on 2nd order ODE's and this will happen every time you use it.

Well if you assume that the C.F. of has the form of then the following steps of:
