Help solving dy/dx= 2x-y?

how do i use the method of Taylor series to solve
dy/dx= 2x-y
whilst lettin a=0 in this case (and if you can sum the series, do so)

apparently a general solution with a constant will be found?

please could someone explain this to me?

i cant remember the Taylor series unfortunately (bad i know, as i should know it) but if you look on Youtube and type in Taylor Series, the first vid should be by someone called PatrickJMT, and he is really good at helping you understand things

Implicit or something like that, like differentiate y as normal but then put (dy/dx) in bracket, then re-arrange by getting the dy/dx's on the same side, something like that :tongue:

I did actually give you some hints on how to do this, but the mods seem to have deleted my post! Good luck!
