Statement 2: kh = 132 Hence, [2ab]*[-2(a + b)] = 132 --> ab(a + b) = -33 If a and b are integers, then both ab and (a + b) will be integers. As 33 is odd, both (a + b) and ab must be odd. But that is not possible. Hence, a and b are not integers. You used the contradiction method here to prove insu...
