integral of ((x^3-2x^2+5x))/(x^2)

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

\frac{x ^{2}}{2} - 2 x + 5 ln ∣ x ∣ + C

Solution steps

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

Expand

\frac{x ^{3} - 2 x ^{2} + 5 x}{x ^{2}} : x - 2 + \frac{5}{x}

= \int x - 2 + \frac{5}{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 x d x - \int 2 d x + \int \frac{5}{x} d x

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

\int 2 d x = 2 x

\int \frac{5}{x} d x = 5 ln ∣ x ∣

= \frac{x ^{2}}{2} - 2 x + 5 ln ∣ x ∣

Add a constant to the solution

= \frac{x ^{2}}{2} - 2 x + 5 ln ∣ x ∣ + C

\int \frac{x ^{2}}{( x ^{2} + 100 ) ^{\frac{3}{2}}} d x

\int tan^{7} (x) sec^{6} (x) d x

\int 4 sin (2 x) cos (2 x) d x

\int \frac{( 4 x - 1 )}{( 2 x + 1 ) ^{\frac{3}{2}}} d x

\int 10 csc^{2} (- 5 x) cot^{4} (- 5 x) d x
