integral of-7/(x^2)-4

Solution

\int - \frac{7}{x ^{2}} - 4 d x

Solution

\frac{7}{x} - 4 x + C

Solution steps

\int - \frac{7}{x ^{2}} - 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{7}{x ^{2}} d x - \int 4 d x

\int \frac{7}{x ^{2}} d x = - \frac{7}{x}

\int 4 d x = 4 x

= - (- \frac{7}{x}) - 4 x

Simplify

= \frac{7}{x} - 4 x

Add a constant to the solution

= \frac{7}{x} - 4 x + C
