The reason why it does not matter if a, b, c, d are positive or negative is that you are for the most part working with even powers and in that case, if you have negative numbers in the numerals they will become positive numbers as noted because simply is going to give us positive values no matter is it is positive or negative.

If you are stuck on the question, here's a thread with a worked solution

Part B/C - Algebraic Inequalities

I completed part a a) a^4+b^4 ≥ 2a^2b^2 etc. for part b though, I'm unsure what it would be following the same logic
