hello everyone, im trying to do a voltage analysis for some electric circuit in my homework assingment and deduced the following equation:

(a - v(t) )^2 = c*v'(t)

a,c - constants

now i dont remember much from the differential equations course i took in first year, but i dont think we learned how to solve a none linear equation

so can anyone explain to me how to solve such a thing ?

thanks
