Nov 18, 2017 at 6:10 | comment | added | Daniel R. Collins | If one needs a resource on factoring polynomials in integers at the high school level, then I can recommend OpenStax Elementary Algebra, Chapter 7. cnx.org/contents/[email protected]:UovuKZl2@3/… | |
Nov 17, 2017 at 23:12 | comment | added | user507 | I would have had no idea what was being asked in the factoring question. | |
Oct 31, 2017 at 12:54 | comment | added | Daniel R. Collins | @DRF: The expected factoring is in integers (see various high school standards for Algebra I). The expected answer is $2(5a^2+3b)(5a^2−3b)$. None of the student responses involved radical expressions. | |
Oct 31, 2017 at 8:38 | comment | added | DRF | What should be the correct answer to that question? $2(5a^2+3b)(\sqrt{5}a-\sqrt{3b})(\sqrt{5}a+\sqrt{3b})$? That seems like a nasty and tricky to interpret question to be honest. | |
