Suppose ... charley\u0027s webWebA Simple Proof by Contradiction Theorem: If n2 is even, then n is even. Proof: By contradiction; assume n2 is even but n is odd. Since n is odd, n = 2k + 1 for some integer k. Then n2 = (2k + 1)2 = 4k2 + 4k + 1 = 2(2k2 + 2k) + 1. Now, let m = 2k2 + 2k. Then n2 = 2m + 1, so by definition n2 is even. But this is clearly impossible, since n2 is even. hartcrown groundworks
