A quadratic field is a specific type of number field that is generated by adjoining a square root of a rational number to the field of rational numbers, \\(\\mathbb\{Q\}\\). More formally, a quadratic field can be expressed in the form: \\\[ K = \\mathbb\{Q\}(\\sqrt\{d\}) \\\] where \\(d\\) is a square-free integer (an integer not divisible by a perfect square greater than 1).
