(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[tex]f(x) = x^3 + x^2 - 11x^2 -9x +18[/tex]

when

[tex]f(x) = 6[/tex]

2. Relevant equations

Using Mathcad

Polyroots, solve function,

3. The attempt at a solution

I dont know how to paste mathscad, but i can get solution using polyroots for

[tex]f(x) = 0[/tex]

I dont know how to modify the mathscad code so that i can get

[tex]f(x) = 6[/tex]

I know how to use the basic root, polyroot and solve functions.

I have done an X/Y graph, but cant seem to get 6 on the y axis, always a little over or under.

Help is really, really appreciated, needed a.s.a.p,

Thanks
