[AISL][AIHL] Tuesday Tests: Quadratics

It's Tuesday Tests and I'm back with two more tests for AISL and AIHL folks.

The AIHL test is pretty similar to the AA tests because y'all need a solid foundation of algebra to do well in the course.

AISL is different in nature. I recognise that not everyone needs to master algebra to the same level as AIHL and that you don't really need too much algebra to get a high 7. By this I don't mean AISL is in any way inferior to AASL; it's simply a difference in the focus of the course. 

So here you go.
