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

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

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

Solution steps

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

Take the constant out:

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

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

Apply u-substitution

: \int - \frac{1}{8 u ^{2}} d u

= 2 \cdot \int - \frac{1}{8 u ^{2}} d u

Take the constant out:

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

= 2 (- \frac{1}{8} \cdot \int \frac{1}{u ^{2}} d u)

Apply the Power Rule

: - \frac{1}{u}

= 2 (- \frac{1}{8} (- \frac{1}{u}))

Substitute back

u = 3 - 4 x^{2}

= 2 (- \frac{1}{8} (- \frac{1}{3 - 4 x ^{2}}))

Simplify

2 (- \frac{1}{8} (- \frac{1}{3 - 4 x ^{2}})) : \frac{1}{4 ( - 4 x ^{2} + 3 )}

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

Add a constant to the solution

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

\int 1 + \frac{( 4 x ^{4} - 1 ) ^{2}}{16 x ^{4}} d x

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

\int \frac{8 x}{2 x + 7} d x

\int \frac{2 e ^{x}}{e ^{3 x} + 2 e ^{x}} d x

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