Algebra, V, p. 18, § 3. Algebraic extensions

With the notation of Th. 2, E=K[a1,a2,...,an]E = K[a_1, a_2, ..., a_n] and hence EE is isomorphic to a quotient K[X1,X2,...,Xm]/aK[X_1, X_2, ..., X_m]/\mathfrak{a}; since EE is a field, aa is a maximal ideal in K[X1,...,Xm]K[X_1, ..., X_m].

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
