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

\int (\frac{4 x ^{2} + 7 x}{x ^{2}}) d x

4 x + 7 + 7 ln ∣ x ∣ + C

Solution steps

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

Apply Integration By Parts

: 4 x + 7 - \int - \frac{7}{x} d x

= 4 x + 7 - \int - \frac{7}{x} d x

\int - \frac{7}{x} d x = - 7 ln ∣ x ∣

= 4 x + 7 - (- 7 ln ∣ x ∣)

Simplify

= 4 x + 7 + 7 ln ∣ x ∣

Add a constant to the solution

= 4 x + 7 + 7 ln ∣ x ∣ + C

\int a e^{7 x} d x

\int \frac{1}{x ( 25 + ln ^{2} ( x ) )} d x

\int x^{- 2} ln (- \frac{5}{3} x) d x

\int 7 cot^{5} (x) d x

\int sin (6 e^{x}) d x
