I should use quotation marks instead of parnethesis?

yes

anonymous · Answer

The second sentence combines two complete sentences with a conjunction (and) but leaves out the required punctuation (a comma).  That's called a coordinating conjunction.  You need both the comma and the conjunction.  The comma would go after the end parentheses since it is part of the first sentence.

well there's a punctuation error by and

you put commas before coordinating conjuctions that links two independent clauses together ALWAYS
