Of course, I realise that practice is very important
But does anyone have any "Tips and Tricks" to share when approaching these problems Eg. Watching out for the use of factorization (a^2 - B^2) = (a-b)(a+b)

Not sure if I have any tips as such, but one mistake that a lot of people do is "magically" cancelling down fractions when in fact it doesn't work.
does not equal
I'm sure there's a better example out there which is easier to make this mistake in.
But you get the point. Don't make that mistake
Show all your working.
If you want to divide the numerator by something, "something" must be a factor of everything in every part of the numerator.
