如果a+b=7，請問a^2+2ab+b^2+(a+1)(b+1)等於多少？

最佳解答： The attached is the recommendation to seek your approval. 華語譯：附件是尋求(徵求)您的批准(承認)的建議(推薦)。
1. 主詞的形式，沒有形容詞、動詞的用法，而需以 "the + 形容詞、分詞"、"動名詞"、"不定詞" 的形式表現。
2. "to be seek(v.)" 不符合文法，以 "to seek" 不定詞就符合文法。
# "to be" 通常是 "to be + 形容詞" 表現。

I have attached my recommendation (for your reference).
Also, all the items have been approved by my acting head, Lily.

最佳解答： No. Ctrip is in control of the ticket.

So Ctrip says no, it is a firm no.
