integral of ln^2(2x^2)

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

x (ln (2) + 2 ln (x))^{2} - 4 (x (ln (2) + 2 ln (x)) - 2 x) + C

Solution steps

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

Apply Integration By Parts

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

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

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

= x ln^{2} (2 x^{2}) - 4 (x (ln (2) + 2 ln (x)) - 2 x)

Simplify

ln (2 x^{2}) : 2 ln (x) + ln (2)

= x (ln (2) + 2 ln (x))^{2} - 4 (x (ln (2) + 2 ln (x)) - 2 x)

Add a constant to the solution

= x (ln (2) + 2 ln (x))^{2} - 4 (x (ln (2) + 2 ln (x)) - 2 x) + C

\int \frac{9 x}{6 x ^{2} + 10} d x

\int 8 x^{3} e^{x^{2}} d x

\int \frac{x ^{5}}{x ^{6} + 9} d x

\int \frac{x ^{2} + 2 x}{x ^{3} + 3 x ^{2} + 4} d x

\int x^{4} 13 + x^{5} d x
