For #9 shouldn't you divide out the 6 from the numerator and denominator?
For #13 shouldn't you subtract 81 from both sides instead of adding, so the answer is (n-9)^2 -148? I checked with the -b/2a method and I got (9, -148). But I also have an A- in algebra 2 💀soooo.

Other than that this video was really helpful I had no clue about determinants in matrices, probably cause I haven't gotten that far yet:))))
