Any even number multiplied by itself and an even number multiplied by another even number minus abd even number is always even which will leave you with an even number when you start with an even.
Example
4sqaured = 16 (even) - 4 (even) =12 (even)
However sometimes odd numbers sqaured are odd numbers for example 7 multiplied by 7 =49 (odd) but any odd number - itself will always be even.
