Cu2+ + 2 OH- >> Cu(OH)2

The charge on the Copper is 2+, and the charge on the Hydroxide ion is 1-. So for electrical neutrality, each Cu2+ needs 2 OH-. Use parentheses on the OH, like this:

Cu2+ + 2 OH- --> Cu(OH)2

When you write the formula, there should be no charge signs on it, if you've balanced out the charges already.

Cu2+ + 2 OH- -----> Cu(OH)2

No.

Cu++ + 2OH- ===> Cu(OH)2(s)
