\underline{\textbf{Given:}}

\mathsf{\displaystyle\int\,\dfrac{5x+4}{2x+1}\,dx}

\underline{\textbf{To find:}}

\mathsf{\displaystyle\int\,\dfrac{5x+4}{2x+1}\,dx}

\underline{\textbf{Solution:}}

\mathsf{Consider,}

\mathsf{\displaystyle\int\,\dfrac{5x+4}{2x+1}\,dx}

\textsf{This can be written as}

\mathsf{=\displaystyle\int\,\dfrac{\dfrac{5}{2}(2x+1)+\dfrac{3}{2}}{2x+1}\,dx}

\mathsf{=\displaystyle\int\,\left[\dfrac{\dfrac{5}{2}(2x+1)}{2x+1}+\dfrac{\dfrac{3}{2}}{2x+1}\right]\,dx}

\mathsf{=\displaystyle\int\dfrac{\dfrac{5}{2}(2x+1)}{2x+1}\,dx+\displaystyle\int\dfrac{\dfrac{3}{2}}{2x+1}\,dx}

\mathsf{=\displaystyle\dfrac{5}{2}\int\,dx+\dislaystyle\dfrac{3}{2}\int\dfrac{1}{2x+1}\,dx}

\mathsf{=\dfrac{5}{2}+\dfrac{3}{2}.\dfrac{1}{2}\,log|2x+1|+C}

\mathsf{=\dfrac{5}{2}+\dfrac{3}{4}\,log|2x+1|+C}

\underline{\textbf{Find more:}}
