integral of (2x+2/(x^2))

\int (2 x + \frac{2}{x ^{2}}) d x

x^{2} - \frac{2}{x} + C

Solution steps

\int 2 x + \frac{2}{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 x d x + \int \frac{2}{x ^{2}} d x

\int 2 x d x = x^{2}

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

= x^{2} - \frac{2}{x}

Add a constant to the solution

= x^{2} - \frac{2}{x} + C

\int \frac{x}{x ^{2} + 14} d x

\int (1 + tan (3 t))^{3} sec^{2} (3 t) d t

\int cos^{7} (6 x) sin (6 x) d x

\int \frac{x}{( 3 x + 4 ) ^{2}} d x

\int x^{4} - 1 x^{3} d x
