(xdx)/((x-1)(x-2))

If int(xdx)/((x-1)(x+1)(x-2))=(lambda_(1))/(6)ln|x+1|+(lambda_(2))/(2)ln|x-1|+(lambda_(3))/(3)ln|x-2|+C then which is/are true?

int_0^1(xdx)/((2x+1)(x+1))

" 2.Evaluate "int(xdx)/((1+x^(2))

int(2xdx)/((x^(2)+1)(x^(2)+2))

int (xdx)/((x+1)(2x + 1))

int(xdx)/((1+x)^(1/2)

int(xdx)/((1-x^(2))^(3/2))
