Eisenstein's criterion tells if certain types of t
Eisenstein's criterion tells if certain types of these are irreducible over the rational numbers. If they involve only one variable, these objects will have at most n1 ["n minus 1"] extrema and n2 ["n minus 2"] inflection points if they are of degree n. One over x is (*) not this type of expression, because the exponent on the variable must be a positive integer. For 10 points, name this type of mathematical expression, exemplified by quadratics such as x squared plus 3x minus 5.
