algebraically closed field

[¦al·jə¦brā·ik·lē ¦klōzd ′fēld]
(mathematics)
A field F such that every polynomial of degree equal to or greater than 1 with coefficients in F has a root in F.
A field F is said to be algebraically closed in an extension field K if any root in K of a polynominal with coefficients in F also lies in F. Also known as algebraically complete field.
