integral of (125)/((5x-300)^2)

\int \frac{125}{( 5 x - 300 ) ^{2}} d x

- \frac{5}{x - 60} + C

Solution steps

\int \frac{125}{( 5 x - 300 ) ^{2}} d x

Take the constant out:

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

= 125 \cdot \int \frac{1}{( 5 x - 300 ) ^{2}} d x

Apply u-substitution

: \int \frac{1}{5 u ^{2}} d u

= 125 \cdot \int \frac{1}{5 u ^{2}} d u

Take the constant out:

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

= 125 \cdot \frac{1}{5} \cdot \int \frac{1}{u ^{2}} d u

Apply the Power Rule

: - \frac{1}{u}

= 125 \cdot \frac{1}{5} (- \frac{1}{u})

Substitute back

u = 5 x - 300

= 125 \cdot \frac{1}{5} (- \frac{1}{5 x - 300})

Simplify

125 \cdot \frac{1}{5} (- \frac{1}{5 x - 300}) : - \frac{5}{x - 60}

= - \frac{5}{x - 60}

Add a constant to the solution

= - \frac{5}{x - 60} + C

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

\int x arctan (x) d x

\int \frac{3}{1 + 9 x ^{2}} d x

\int \frac{1}{x ^{2} 9 x ^{2} + 1} d x

\int x sin (3 x - 1) d x
