Indefinite Integration

$\frac{7}{\mathrm{a}+\mathrm{b}}\left(\frac{x-\mathrm{b}}{x+\mathrm{a}}\right)^{\frac{9}{7}}+\mathrm{c}$, where c is the constant of integration.

$\frac{7}{a+b}\left(\frac{x-b}{x+a}\right)^{\frac{5}{7}}+c$, where $c$ is the constant of integration.

$\frac{7}{2(a+b)}\left(\frac{x-b}{x+a}\right)^{\frac{2}{7}}+c$, where $c$ is the constant of integration.

$\frac{7}{a+b}\left(\frac{x-b}{x+a}\right)^{\frac{1}{7}}+c$, where $c$ is the constant of integration.
