methods help me? Or any other method?
How about plotting the function? If you write it as f(x) = x^100 - ...
- 6*x - 4000, then clearly f(0) is negative, and large enough x will be
positive. Just find
out what "large enough" means (it depends on the ...) and use that to
start uniroot().

Hi R,
I have a 100th order equation for which I need to solve the value for x. Is
there a package to do this?
For example my equation is:
(x^100 )- (2*x^99) +(10*x^50)+.............. +(6*x ) = 4000
I have only one unknown value and that is x. How do I solve for this?
uniroot() will find one root. If you want all of them, I don't know
what is available.
