bất phương trình

1. (mathematics) an inequation

• Similarly to a phương trình (“equation”), a bất phương trình' is to be solved, which means the specific value(s) or range(s) of values of its unknown(s) must be determined. Compare with a bất đẳng thức (“inequality”) which is not to be solved, but to be proven.
