integral of ((ln(x))2)/x

\int \frac{( ln ( x ) ) 2}{x} d x

ln^{2} (x) + C

Solution steps

\int \frac{ln ( x ) \cdot 2}{x} d x

Take the constant out:

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

= 2 \cdot \int \frac{ln ( x )}{x} d x

Apply u-substitution

= 2 \cdot \int u d u

Apply the Power Rule

= 2 \cdot \frac{u ^{2}}{2}

Substitute back

u = ln (x)

= 2 \cdot \frac{ln ^{2} ( x )}{2}

Simplify

2 \cdot \frac{ln ^{2} ( x )}{2} : ln^{2} (x)

= ln^{2} (x)

Add a constant to the solution

= ln^{2} (x) + C
