integral of ((x^4-5x^3+7x)/x)

\int (\frac{x ^{4} - 5 x ^{3} + 7 x}{x}) d x

\frac{x ^{4}}{4} - \frac{5 x ^{3}}{3} + 7 x + C

Solution steps

\int \frac{x ^{4} - 5 x ^{3} + 7 x}{x} d x

Simplify

\frac{x ^{4} - 5 x ^{3} + 7 x}{x} : x^{3} - 5 x^{2} + 7

= \int x^{3} - 5 x^{2} + 7 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^{3} d x - \int 5 x^{2} d x + \int 7 d x

\int x^{3} d x = \frac{x ^{4}}{4}

\int 5 x^{2} d x = \frac{5 x ^{3}}{3}

\int 7 d x = 7 x

= \frac{x ^{4}}{4} - \frac{5 x ^{3}}{3} + 7 x

Add a constant to the solution

= \frac{x ^{4}}{4} - \frac{5 x ^{3}}{3} + 7 x + C

\int cos^{4} (θ) sin^{2} (θ) d θ

\int 225 - 9 x^{2} d x

\int e^{- 4 x} + x + (4 x + 1) d x

\int sin^{6} (3 x) cos^{2} (3 x) d x

\int x e^{4} d x
