Z 31 (9+x) 2 dxWe make the substitution u = 9+x. As before,du =dudxdxand sowith u = 9+x anddudx= 1It follows thatdu =dudxdx = dxThe integral becomesZ x=3x=1 u 2 duwhere we have explicitly written the variable in the limits of integration to emphasise that thoselimits were on the variable x and not u.
