Also known as a fractional expression. For one-variable or multivariable polynomials P and Q , when Q ≠ 0 ( polynomial Q being 0 means that all coefficients are 0), this is an expression of the form. Here, just as with fractions, when P1Q2 = P2Q1 , we consider P1 / Q1 = P2 / Q2 . By substituting the variable x for the indeterminate element X of f ( X ), we can consider the rational function f ( x ) = P ( x )/ Q ( x ), but in this case the zero points of Q must be excluded from the domain of definition . In high school mathematics textbooks, there are cases where the nuance of f ( x ) is stronger and cases where the nuance of f ( X ) is stronger.

分数式ともいう。1変数または多変数の多項式 P ,Q について,Q≠0 のとき (多項式 Q が 0とは,すべての係数が 0を意味する) , の形の式をいう。ここで,分数のときと同じく,P1Q2=P2Q1 のとき,P1/Q1=P2/Q2 と考える。 f(X) の不定元 X に変数 x を代入すると,有理関数 f(x)=P(x)/Q(x) が考えられるが,こちらの場合は Q の零点を定義域から除外しなければならない。高校数学の教科書では,f(x) のニュアンスの強い場合と,f(X) のニュアンスの強い場合とがある。
