we want to integrate the following expression, the angle of two D X divided by x squared plus X plus 20. This question is challenging our knowledge of econometric techniques or rather integration techniques, effective, particularly work out as I just hinted that it specifically testing our knowledge of econometric integral or inverse trig intervals. These are on the left one integral. Do you over a squared on issues Security are signing over april C. And on the right to internal D. You over a squared plus you. Spirit is one of the A. R. Tend to be over april. See, we see that because we have no square are denominated for integral. Are integral to the forum. To that we now have to determine you do you and a to proceed for using to we have to you or you is excellent for do you then is the X and A. Is two. That are integral. Has an extra factor of two. We have to carry over to the solution that means are integral is two times the answer with the X over four plus X plus four squared equals two over a arc tangent over april C or arc tangent experts for over two plus, see the content of integration.
