I have a certain mathematical formula that is long enough that LaTeX breaks it into two lines, with a mere two characters wrapping to the second line. I would like to force LaTeX to display this as a single line of standard width, by condensing (negative kerning) all spaces uniformly. Enclosing the whole formula in {} is not the desired solution; this typesets as a single over-width line, rather than a line condensed to fit properly. Is there any method that will work?
In response to David Carlisle's comment, the context is indeed inline math, but as an \item in an itemize environment, so the inline math constitutes a full line of text by itself. Notably, this means that if you force the overfull hbox typesetting using {}, the formula becomes a new line below the itemize bullet, whereas I want it to fit in the space to the right of the bullet.

\usepackage{microtype}?\thicmuskipand\medmuskipto reduce math space, but without any example code hard to give any specific advice{...}or\begin{something}...\end{something}or if grouping isn't appropriate just set them before the equation and set them back afterwards
