integral of 4/((2x-5)^3)

\int \frac{4}{( 2 x - 5 ) ^{3}} d x

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

Solution steps

\int \frac{4}{( 2 x - 5 ) ^{3}} d x

Take the constant out:

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

= 4 \cdot \int \frac{1}{( 2 x - 5 ) ^{3}} d x

Apply u-substitution

= 4 \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

= 4 \cdot \frac{1}{2} \cdot \int \frac{1}{u ^{3}} d u

Apply the Power Rule

= 4 \cdot \frac{1}{2} (- \frac{1}{2 u ^{2}})

Substitute back

u = 2 x - 5

= 4 \cdot \frac{1}{2} (- \frac{1}{2 ( 2 x - 5 ) ^{2}})

Simplify

4 \cdot \frac{1}{2} (- \frac{1}{2 ( 2 x - 5 ) ^{2}}) : - \frac{1}{( 2 x - 5 ) ^{2}}

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

Add a constant to the solution

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