The integral `inte^x(f(x)+f\'(x))dx` can be solved by using integration by parts such that: `I=inte^xf(x)dx+inte^xf\'(x)dx=e^xf(x)-inte^xf\'(x)dx+inte^xf\'(x)dx=e^xf(x)+C` , and `inte^(ax)(f(x)+(f\'(x))/a)dx=e^(ax)f(x)/a+C` ,Now answer the question:`int(e^x(2-x^2))/((1-x)sqrt(1-x^2))dx` (A) `e^xsqrt((1-x)/(1+x))+C` (B) `e^xsqrt((1+x)/(1-x))+C` (C) `e^xsqrt((2-x)/(2+x))+C` (D) none of these
