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

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

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

Solution steps

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

Take the constant out:

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

= 3 \cdot \int \frac{1}{( 1 - 2 x ) ^{3}} d x

Apply u-substitution

= 3 \cdot \int - \frac{1}{2 u ^{3}} d u

Take the constant out:

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

= 3 (- \frac{1}{2} \cdot \int \frac{1}{u ^{3}} d u)

Apply the Power Rule

= 3 (- \frac{1}{2} (- \frac{1}{2 u ^{2}}))

Substitute back

u = 1 - 2 x

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

Simplify

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

= \frac{3}{4 ( 1 - 2 x ) ^{2}}

Add a constant to the solution

= \frac{3}{4 ( 1 - 2 x ) ^{2}} + C
