integral of ((x^2-2x+1)^{1/5})/(1-x)

\int \frac{( x ^{2} - 2 x + 1 ) ^{\frac{1}{5}}}{1 - x} d x

- \frac{5}{2} (x - 1)^{\frac{2}{5}} + C

Solution steps

\int \frac{( x ^{2} - 2 x + 1 ) ^{\frac{1}{5}}}{1 - x} d x

Complete the square

x^{2} - 2 x + 1 : (x - 1)^{2}

= \int \frac{( ( x - 1 ) ^{2} ) ^{\frac{1}{5}}}{1 - x} d x

Apply u-substitution

: \int - \frac{1}{u ^{\frac{3}{5}}} d u

= \int - \frac{1}{u ^{\frac{3}{5}}} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \int \frac{1}{u ^{\frac{3}{5}}} d u

Apply the Power Rule

: \frac{5}{2} u^{\frac{2}{5}}

= - \frac{5}{2} u^{\frac{2}{5}}

Substitute back

u = x - 1

= - \frac{5}{2} (x - 1)^{\frac{2}{5}}

Add a constant to the solution

= - \frac{5}{2} (x - 1)^{\frac{2}{5}} + C

\int x sin^{2} (9 x) d x

2 x^{\frac{3}{2}}

\int sin^{3} (5 x) cos^{- 2} (5 x) d x

\int_{1}^{2} \frac{x ^{2} + 7}{3 x - x ^{2}} d x

\frac{s}{( 2 s + 1 ) ( ( s + 2 ) ^{2} - 1 )}
