This is not a homework question, I'm not trying to get an answer to solve this problem. I just need to know what this kind of algebra one problem is called.

Numbers 1 & 2 are called quadratic equations. Number 3 is long division of polynomials.

This is algebra-precalculus, and if I had to give a general name to all the three problems you're given, I'd say they are problems related to “polynomials.” Otherwise, yes, the first two are quadratic equations and the third one is polynomial division, as Saladsamurai said.
