integral of (8x+15)ln(2x)

\int (8 x + 15) ln (2 x) d x

4 x^{2} ln (2 x) + 15 x ln (2 x) - 2 x^{2} - 15 x + C

Solution steps

\int (8 x + 15) ln (2 x) d x

Apply Integration By Parts

: ln (2 x) (4 x^{2} + 15 x) - \int 4 x + 15 d x

= ln (2 x) (4 x^{2} + 15 x) - \int 4 x + 15 d x

\int 4 x + 15 d x = 2 x^{2} + 15 x

= ln (2 x) (4 x^{2} + 15 x) - (2 x^{2} + 15 x)

Simplify

ln (2 x) (4 x^{2} + 15 x) - (2 x^{2} + 15 x) : 4 x^{2} ln (2 x) + 15 x ln (2 x) - 2 x^{2} - 15 x

= 4 x^{2} ln (2 x) + 15 x ln (2 x) - 2 x^{2} - 15 x

Add a constant to the solution

= 4 x^{2} ln (2 x) + 15 x ln (2 x) - 2 x^{2} - 15 x + C

\int t^{2} e^{- 9 t} d t

\int_{1}^{4} \frac{3 ln ( x )}{x ^{2}} d x

\frac{d}{d x} (\frac{x ^{4}}{9})

y = 2916 x, 108 x^{2}

\int \frac{x ( 2 x - 9 )}{x ^{3} - 6 x ^{2} + 12 x - 8} d x
