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

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

- \frac{7}{x} - 2 ln ∣ x ∣ + C

Solution steps

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

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

\int \frac{2}{x} d x = 2 ln ∣ x ∣

= - \frac{7}{x} - 2 ln ∣ x ∣

Add a constant to the solution

= - \frac{7}{x} - 2 ln ∣ x ∣ + C

\int 8 x^{2} + 1 d x

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

\int (sec (4 x) - csc (\frac{2 x}{3})) d x

\int \frac{9 x ^{8} + 6}{( x ^{9} + 6 x ) ^{2}} d x

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