[unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula]
I can do this like - you know - finding the common denominator and stuff... But I feel that I am missing a trick!

What is the sum of the roots taken two at a time? I know this but I don't - I keep putting the opposite sign for the answer... How do I do this???
The set [unparseable or potentially dangerous latex formula] has [unparseable or potentially dangerous latex formula] subsets with an even number of elements. [unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula]

The reciprocal of [unparseable or potentially dangerous latex formula] is [unparseable or potentially dangerous latex formula]. Find [unparseable or potentially dangerous latex formula].
[unparseable or potentially dangerous latex formula] Find [unparseable or potentially dangerous latex formula]
I usually do the ones with the "find a" or "find b" pretty quickly. But these take a bit longer and I get them wrong most of the time... Is there a trick?
What is the modulus exactly? What is it for the square roots? For example:
Modulus of [unparseable or potentially dangerous latex formula] = ?
Modulus of [unparseable or potentially dangerous latex formula] = ?
Is there a faster way of dividing the complex numbers other than just multiplying by conjugates?
