Finding root of quadratic equation
2 messages · gmasyata, R. Michael Weylandt
Hi Sveta, This is pretty self-evidently homework (and rather odd homework at that) so I'm afraid it's the policy of the list not to give you a hand. We can never be quite sure what your teacher wants you to learn from any given assignment and we don't want to undermine the education that you are paying for. Good luck though! Michaewl

Dear R Helpers, I need to find the root of following equationy=x^2+3*x-1 by substitution a random number from less to more in the certain segment.I had tried using this codef <- function (x) x^2+x-12str(xmin <- uniroot(f, c(2, 4), tol = 0.0001)) but $ f.root : num -7.85e-07not 0, and so I'm not shure it's right code and satisfactory answer.
