Could someone explain me this simplification?
I cannot understand exact reason why $c_1$ is before $\exp$ function without being in another one.
Screenshot presents end of solution of this differential equation: $$\frac{{\rm d}y}{{\rm d}x}=(x^2−2)(y−4)$$
I will be very grateful for the solution of it entirely with all the steps even in the form of a photo of a sheet of paper
