Product over sum.
So, taking signs into account, that's +10 times -6 (giving -60) divided by (+10 plus -6) or +4. Result is thus -15.
So the resulting reactance is 15 ohms, and being negative, it is capacitive reactance.
I'm carrying on with this fairly late at night as my theory could be improved a bit. There's some information on power factors and resistors combined with reactances. It also tells you how to work out the resonant frequency - my calculator helps.
