Good that I haven't given an earlier answer, which would have
considered sloppypar only -- I deem sloppypar a worse solution.
I would like to improve Karl's second answer, about as follows:
(... in the document preamble). Then place that \nobreakf
in each "shortish" formula, i.e., inside $...$ or \(...\);
you can place it right before the second $ or before the \).
(Be sure to use `\nobreakf', not `\nobreak'.)
I have tested this (instead of trying to understand the TeXbook;
test: `\hsize .33em'; then `$X=Y\nobreakf$' does).
It seems to suffice indeed to put \nobreakf anywhere
inside such a formula. Other line breaks (even within the same
paragraph) then seem not to be affected.
