I may just be overlooking something here but...
4-(1/x)-(2/x^2)=0
converts to
(4x^2)-(1x)-2=0
if you multiply the first one by x^2
BUT! they do not graph the same.
BUT! to make it easy to work in the quadratic equation you have to multiply the original by x^2
what gives?
are there characteristics to equations that are not addressed by the distribution and order of operations properties, or did i just miss something?
the answer book said this method was correct.
and this is not for homework BTW. I already graduated university and am in the process of going over all the math i took back in school, college algebra especially as i took it in a 20 day may course. I want to go past the calculus book this time so I'm taking it slow and asking all the questions i need to.
