c + c²
= c (1 + c)
= c (1 + c)
For any positive integer
c (1 + c) = even (odd) or odd(even)
even + 1 = odd
odd + 1 = even
Therefore c (1 + c) will always be even because anything multiple by an even number is even
c (1 + c) = even (odd) or odd(even)
even + 1 = odd
odd + 1 = even
Therefore c (1 + c) will always be even because anything multiple by an even number is even
