integral of (-3x^{-2})

\int (- 3 x^{- 2}) d x

\frac{3}{x} + C

Solution steps

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

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

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

Apply the Power Rule

: - \frac{1}{x}

= - 3 (- \frac{1}{x})

Simplify

- 3 (- \frac{1}{x}) : \frac{3}{x}

= \frac{3}{x}

Add a constant to the solution

= \frac{3}{x} + C

\int \frac{e ^{x}}{e ^{x} - 3} d x

\int \frac{x}{x ^{2} + 10} d x

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

\int 5 e^{x} sin (2 x) d x

\int 8 x (2 x - 1)^{4} d x
