integral of ((x^4-2x^3+1))/(x^2)

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

\frac{x ^{3}}{3} - x^{2} - \frac{1}{x} + C

Solution steps

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

Expand

\frac{x ^{4} - 2 x ^{3} + 1}{x ^{2}} : x^{2} - 2 x + \frac{1}{x ^{2}}

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

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

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

\int \frac{1}{x ^{2}} d x = - \frac{1}{x}

= \frac{x ^{3}}{3} - x^{2} - \frac{1}{x}

Add a constant to the solution

= \frac{x ^{3}}{3} - x^{2} - \frac{1}{x} + C

\frac{d}{d x} (cos^{4} (\frac{x}{4}))

\int (14 x + 1) 7 x^{2} + x d x

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

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

e^{- \frac{t}{4}}
