would you possibly be able to show me a step by step solution for the following?? Integrate: 2x((x^2)+1)^23 dx with respect to x thanks Dave

Integrate: 2x((x^2)+1)^23 dx with respect to x thanks Dave Try the u substition $\displaystyle u=x^2+1$ then $\displaystyle du=2xdx$ so making the substition $\displaystyle \int 2x(x^2+1)^{23}dx=\int u^{23}du=\frac{1}{24}u^{24}+C$ subbing u back in we get... $\displaystyle \frac{1}{24}(x^2+1)^{24}+C$
