Hey
Thanks for your reply
Ok I expanded the brackets dividing the whole thing by 1000 first
...very tedious method used Pascals triangle
Then I collected the like terms together this is what I got.. (I hope I didn’t make a mistake!!)
Then divided the whole thing by 0.5
LOL after all that I’m still nowhere close to the answer 13.45%...
I’m I going the right way about this.. surely there is a simpler method?
that is not right. dividing through by 100 and expanding everything, we get:
i am sorry, but i do not see a nice way to solve this. there is no general formula for solving general polynomials of degree 5 or above. and this guy does not look like a nice guy to factor.
so yeah, there is no general formula for solving quintic polynomials. if you can use technology for this, do so. otherwise, this question is just mean.
