integral of x*(2x+5)^{10}

\int x \cdot (2 x + 5)^{10} d x

\frac{1}{528} (11 (2 x + 5)^{12} - 60 (2 x + 5)^{11}) + C

Solution steps

\int x (2 x + 5)^{10} d x

Apply u-substitution

: \int \frac{u ^{10} ( u - 5 )}{4} d u

= \int \frac{u ^{10} ( u - 5 )}{4} d u

Take the constant out:

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

= \frac{1}{4} \cdot \int u^{10} (u - 5) d u

Expand

u^{10} (u - 5) : u^{11} - 5 u^{10}

= \frac{1}{4} \cdot \int u^{11} - 5 u^{10} d u

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \frac{1}{4} (\int u^{11} d u - \int 5 u^{10} d u)

\int u^{11} d u = \frac{u ^{12}}{12}

\int 5 u^{10} d u = \frac{5 u ^{11}}{11}

= \frac{1}{4} (\frac{u ^{12}}{12} - \frac{5 u ^{11}}{11})

Substitute back

u = 2 x + 5

= \frac{1}{4} (\frac{( 2 x + 5 ) ^{12}}{12} - \frac{5 ( 2 x + 5 ) ^{11}}{11})

Simplify

\frac{1}{4} (\frac{( 2 x + 5 ) ^{12}}{12} - \frac{5 ( 2 x + 5 ) ^{11}}{11}) : \frac{1}{528} (11 (2 x + 5)^{12} - 60 (2 x + 5)^{11})

= \frac{1}{528} (11 (2 x + 5)^{12} - 60 (2 x + 5)^{11})

Add a constant to the solution

= \frac{1}{528} (11 (2 x + 5)^{12} - 60 (2 x + 5)^{11}) + C

\int cos^{2} (\frac{π x}{2}) d x

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

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

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

\int \frac{x + 2}{x ^{2} - 6 x + 34} d x
