integral of 2/(2x-3)

\int \frac{2}{2 x - 3} d x

ln ∣ 2 x - 3 ∣ + C

Solution steps

\int \frac{2}{2 x - 3} d x

Take the constant out:

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

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

Apply u-substitution

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

Take the constant out:

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

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

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= 2 \cdot \frac{1}{2} ln ∣ u ∣

Substitute back

u = 2 x - 3

= 2 \cdot \frac{1}{2} ln ∣ 2 x - 3 ∣

Simplify

2 \cdot \frac{1}{2} ln ∣ 2 x - 3 ∣ : ln ∣ 2 x - 3 ∣

= ln ∣ 2 x - 3 ∣

Add a constant to the solution

= ln ∣ 2 x - 3 ∣ + C

\frac{d y}{d x} = 2 y + x^{2} + 5

\frac{d y}{d x} + (\frac{4}{x}) y = 4 x + 9
