integral of-9/(x^2)

Solution

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

Solution

\frac{9}{x} + C

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule

= - 9 (- \frac{1}{x})

Simplify

- 9 (- \frac{1}{x}) : \frac{9}{x}

= \frac{9}{x}

Add a constant to the solution

= \frac{9}{x} + C
