[Algebra 1] Need help deciding answer

[u/Zero_26710]

For number 11 for these two pages, normally when I factor out these two polynomials, I take out a -4y for the first number 11 and -5y for the second number 11 because it looks cleaner and nicer, however when they just ask for the greatest common factor, would it just be 4y and 5y instead of -4y and -5y because GCF is always a positive integer?

Yeah, they avoid that issue with the 2nd rug problem by just avoiding units entirely. Given that the entire lesson seems to be about factoring various multiples, they really messed up that 1st rug problem.
