y''=8*y*3 I am supposed to solve this equation by multiplying both sides of the equation with y' , but I don't know what to do thereafter The answer shall be: y=1/(C+-2x) But I don't know how to get it, can anybody tell me the steps?

You can solve using laplace transforms

or actually nevermind you aren't given initial conditions

ok, you just substitute v=y' then using chain rule y''=v*dv/dy. Sub everythign back into original and you get a separable equation with y's and v's
