DEFINITION 9.1.2 A field K is said to be quadratically closed, if every element of
K is a square of an element of K, that is, if K = K2 . A field K is quadratically closed
if and only if the square class group K/K2 is a trivial (1— element) group.

Hence the result. D The field F is called quadratically closed if it has no non-trivial
extensions of degree 2. In particular every element of such a field has a square
root in the field. It is clearly not the case that a subfield of a quadratically closed ...

the matrix K such that (47.30) is quadratically stable. This is the "quadratic
stabilizability" problem. System (47.30) is quadratically stable for some state-

Field and Galois Theory
To see that K is quadratically closed, suppose that L/K is a quadratic extension,
and say L = K(y/a) for some a G K. Then a G E for some finite Galois
subextension E. By the argument above, we have [E : F] = 2r for some r. The
extension E(Va)/E ...

25.4 Newton's Method Converges Quadratically 395 small as possible. The ideal
would be g'(x) = 0. Differentiating the equation g(x) = x — a(x)f(x) with respect to x
, we get g'(x) = 1 - a'(x)f(x) - a(x)f'(x). Assuming that f'(x) ^ 0, and using f(x) = 0, ...

The Algebraic and Geometric Theory of Quadratic Forms
Therefore, we do the two cases separately. 31. A. Nonformally real fields. We
consider the case of nonformally real fields first. A field F is called quadratically
closed if F = F2. For example, algebraically closed fields are quadratically closed.
