integral of (7-2x)^{12}

\int (7 - 2 x)^{12} d x

- \frac{1}{26} (7 - 2 x)^{13} + C

Solution steps

\int (7 - 2 x)^{12} d x

Apply u-substitution

: \int - \frac{u ^{12}}{2} d u

= \int - \frac{u ^{12}}{2} d u

Take the constant out:

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

= - \frac{1}{2} \cdot \int u^{12} d u

Apply the Power Rule

: \frac{u ^{13}}{13}

= - \frac{1}{2} \cdot \frac{u ^{13}}{13}

Substitute back

u = 7 - 2 x

= - \frac{1}{2} \cdot \frac{( 7 - 2 x ) ^{13}}{13}

Simplify

- \frac{1}{2} \cdot \frac{( 7 - 2 x ) ^{13}}{13} : - \frac{1}{26} (7 - 2 x)^{13}

= - \frac{1}{26} (7 - 2 x)^{13}

Add a constant to the solution

= - \frac{1}{26} (7 - 2 x)^{13} + C

\int \frac{x + 1}{x ^{2} + 10 x + 34} d x

\int \frac{- cos ( 3 x )}{1 - sin ( 3 x )} d x

\int \frac{1}{cos ^{2} ( x ) + 4 sin ^{2} ( x )} d x

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

\int \frac{1 + 2 e ^{x}}{e ^{2 x}} d x
