第 12769 題：實雙線性形式

原題與已知條件

雙線性必須分別核第一槽與第二槽。操作=bilinear-second-slot-identity；資料={"matrix":[[6,1],[-3,-4]],"x":[1,1],"u":[1,1],"v":[1,1],"alpha":1,"beta":1}。請依 [alpha,beta,combined,lhs,rhs,equal] 欄序回答。

定義與適用範圍

沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核，並由原始參數逐題獨立重算模型、答案與每個算術步驟；原題仍為 candidate。

逐步推導

fixed real matrix=[[6, 1], [-3, -4]];B(x,y)=sum_i sum_j x_i*A_ij*y_j

distributivity proves real linearity in each slot separately for all vectors and scalars
