I think you have to use the formula: the integral of du/u = ln|u|+C and in this problem u=x+3 and therefore du=dx.

Just observe carefully.... there is a x term in the numerator. So according to you u = x+3, du = dx. So But hey you have to get rid of that x in the above expression Thats why write . Both the terms now are easily integrable
