integral of 2-5/(x^2)

Solution

\int 2 - \frac{5}{x ^{2}} d x

Solution

2 x + \frac{5}{x} + C

Solution steps

\int 2 - \frac{5}{x ^{2}} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 2 d x - \int \frac{5}{x ^{2}} d x

\int 2 d x = 2 x

\int \frac{5}{x ^{2}} d x = - \frac{5}{x}

= 2 x - (- \frac{5}{x})

Simplify

= 2 x + \frac{5}{x}

Add a constant to the solution

= 2 x + \frac{5}{x} + C
