Good afternoon Lisa! Here are my workings for this question.

Thanks!
I believe this is the way many students give the answer, but should it be more correct to put as …..
y = -3 ln |x+2| + 6 ln |x+4| + 4 + 3 ln3 - 6 ln5 ??
otherwise , we are imposing additional condition x>-2.

Sec 4 students have yet to learn that integrate 1 / x is ln |x|.
It’s only taught in the A Levels. 100% of my tuition students learnt it as ln x.
In short, they only learnt integrate 1/x for x > 0 in their syllabus.
