    Are you required to use integration by parts? The obvious way to integrate this is to let y= 1- x^2 so that dy= -2x dx or -\frac{1}{2}dy= x dx, x^2= 1- y and the integral becomes \int \frac{(x^2)(x dx)}{\sqrt{1- x^2}}= -\frac{1}{2}\int\frac{(1- y)dy}{\sqrt{y}} = -\frac{1}{2}\int\frac{(1- y)dy}{y^{\frac{1}{2}}} = -\frac{1}{2}\int \left(y^{-\frac{1}{2}}- y^{\frac{1}{2}}\right)dy.
