sure thing boo thangg
\[0.27 = \frac{ 110^2 }{ (y-111)^2 (y-55) }\]
o wtf

lmaoo hold up gimme a min
What are we doin? +_+ solvin for y?
yes haha
Multiply and divide some things,\[\Large\rm (y-111)^2 (y-55)= \frac{ 110^2 }{0.27 }\]Then I guess expand out all those brackets.
Then you get a cubic.... which.... might be hard to solve :d hmm
wait it's supposed to be (y-110)^2 lol not 111/ but how do u do a cubic? LOL
\[\Large\rm (y-110)^2 (y-55)= \frac{ 110^2 }{0.27 }\]Well you know how you have your nice `quadratic formula` for dealing with squares? x= -b+/-sqrt(b^2-.... Well there is one for cubics, but it's extremely long and complex, not worth using most of the time. We could try applying rational root theorem to find a factor, and then factor it. If it doesn't factor, then..... oh boy +_+
what is the equation for cubic? lol i think my professor wants us to know
i doubt it :) lol http://www.math.vanderbilt.edu/~schectex/courses/cubic/
it's the formula that's taking up two lines
near the top
or you could just cheat and use wolfram +_+ https://www.wolframalpha.com/input/?i=%28y-110%29%5E2%28y-55%29%3D110%5E2%2F0.27
it's a weird solution.. not one we could've come up with just by checking roots and stuff :d
There is probably some calculus techniques you could use to get really close to the solution... blah
