由 (overrightarrow{AP} = overrightarrow{OP} - overrightarrow{OA})，(overrightarrow{PB} = overrightarrow{OB} - overrightarrow{OP})

代入得：(overrightarrow{OP} - overrightarrow{OA} = lambda (overrightarrow{OB} - overrightarrow{OP}))尤文图斯赛事预测

整理得：(overrightarrow{OP} + lambda overrightarrow{OP} = overrightarrow{OA} + lambda overrightarrow{OB})

所以：(overrightarrow{OP} = frac{overrightarrow{OA} + lambda overrightarrow{OB}}{1 + lambda})
