how:
integral: (2x+4)/(x^2+2x+3) with respect to x, of course
integral: (2x+4)/(x^2+2x+3) with respect to x, of course
Try a substitution of u=x+1thanks for the reply.
I get how to take the second one, but what about the first? (2x/((x+1)^2+2))
u=x+1 => x=u-1yeah, but doesn't that still leave an X in the numerator?
