You can use the simple formulas for indefinite integral and apply them in your calculations and get the solution easily.
If f(x), g(x) are two functions of a variable x and k is a constant, then (ii) ∫g (x) dx should be taken as the same in both terms. (i) when you find integral ∫g (x) dx then it will not contain an arbitrary constant. If d/dx {φ(x)) = f(x), ∫f(x)dx = φ(x) + c, where c is called the constant of integration or arbitrary constant.
