(x + 2)2 + (y + 3)2 = 0 where x and y are real numbers.

Each parenthesis is a square number and so MUST be greater than or equal to zero, so their sum can be zero only if each parenthesis is zero.

The square of the expressions in the parentheses can be zero only if the expressions themselves are zero and hence the result.
