integral of 3/(x^2)-5/(x^4)

\int \frac{3}{x ^{2}} - \frac{5}{x ^{4}} d x

- \frac{3}{x} + \frac{5}{3 x ^{3}} + C

Solution steps

\int \frac{3}{x ^{2}} - \frac{5}{x ^{4}} 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 \frac{3}{x ^{2}} d x - \int \frac{5}{x ^{4}} d x

\int \frac{3}{x ^{2}} d x = - \frac{3}{x}

\int \frac{5}{x ^{4}} d x = - \frac{5}{3 x ^{3}}

= - \frac{3}{x} - (- \frac{5}{3 x ^{3}})

Simplify

= - \frac{3}{x} + \frac{5}{3 x ^{3}}

Add a constant to the solution

= - \frac{3}{x} + \frac{5}{3 x ^{3}} + C

\int \frac{2 y ^{2} - 7}{y ^{2}} d y

\int \frac{4 x ^{2} + 1}{x ^{3}} d x

\int (x + 1) \cdot 2 - x d x

\int \frac{1 - 9 x ^{2}}{x ^{2}} d x

\int 7 + x d x
