integral of 1/((a+bx)^2)

\int \frac{1}{( a + b x ) ^{2}} d x

- \frac{1}{b ( a + b x )} + C

Solution steps

\int \frac{1}{( a + b x ) ^{2}} d x

Apply u-substitution

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

= \int \frac{1}{b u ^{2}} d u

Take the constant out:

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

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

Apply the Power Rule

: - \frac{1}{u}

= \frac{1}{b} (- \frac{1}{u})

Substitute back

u = a + b x

= \frac{1}{b} (- \frac{1}{a + b x})

Simplify

\frac{1}{b} (- \frac{1}{a + b x}) : - \frac{1}{b ( a + b x )}

= - \frac{1}{b ( a + b x )}

Add a constant to the solution

= - \frac{1}{b ( a + b x )} + C

y = 5 - 9 x^{2}

\int \frac{1}{16 x ^{4} - 1} d x

\frac{d}{d x} (e^{r (t, x) t})

\int \frac{3 e ^{3 t}}{3 + e ^{3 t}} d t

y = ((25 - x^{2})^{\frac{1}{2}}), y = \frac{4}{3} x, x = 5
