If by "answer" you mean the value of a, then there are two answers: 4 - 2√3, and 4 + 2√3. If you mean that it should be factored, there are two ways to think about it:
- Set the whole thing equal to 0 by subtracting 12. Then you get an irreducible quadratic, i.e. one that does not factor.
- Factor only the left side, and consider each part individually. The left side of this equation factors as (a - 4)2.

What is a square root of a square?
Plus or minus the base. If the base is X and you square it, you get X2. If you take the square root of that, you get Plus or Minus X. This is because X*X equals X2 and -X*-X also equals X2.
If sin2a plus cos2a equals 1 does sin2a minus cos2a equals 1 also ... 2 means square and a means alpha?
No. But sin2a equals 1 minus cos2a ... and ... cos2a equals 1 minus sin2a
