Why is the square of an odd number always odd?

By definition, an odd number is an integer that can be written in the form 2k + 1, for some integer k. This means we can write x = 2k + 1, where k is some integer. So x2 = (2k + 1)2 = 4k2 + 4k + 1 = 2(2k2 + 2k) + 1. Since this logic works for any odd number x, we have shown that the square of any odd number is odd.
