I am giving help on your SECOND question because it requires more thorough skill than the FIRST question.

Factorize a -2 on the right side expression!

NOW you are ready to complete the square, as long as you can identify the needed square term. Focus on the trinomial factor of ;
The missing square term is , and THAT is the term you both add and subtract INSIDE the parentheses.

The grouping added is to emphasise,

And now perform the remultiplication to reverse the previous factorization.
