Can someone give me the solution of that trinomial

    :redface: Can I please have the solution of the trinomial


    in terms of the unknown variable "t"?

    I' ve heard that it can be done in 'mathematica'.

    There is no unknown variable "t". There is an "x" and there is an "m".

    Sorry I meant "m"

    What have you done so far?
  6. May 24, 2006 #5
    I don't understand what you mean. I' ve done nothing.
    I don't have a mathematica I that's what you are asking.
    I don't remember the Horner 'thing' or the polynomial division, and I was wondering if someone could help me.

    I've attached the maple output, you'll be able to see it as soon as one of the mentors approves it. I just didn't have the energy to format it into tex, anyway, this way there's no chance of transcription error.

    with mathematica

    m -> {160 - 80x - 41x^2 - 3x^3 / 8 (20+x) }

    We are solving the equation for x kin terms of m, not for m in terms of x. :)

    cubic equation

    ok :
    solved the equation for x in terms of m

    x^3+(11+(8/3))*x^2 all this can be written as...a



    and you can simplify it however you please. i don't see the difficulty since the cubic part didn't have an m in it lol.
