Sure! Let's break down each set into roster form: (i) For set A, we're looking for positive integers less than 10 where 2x - 1 is an odd number. A = {1, 2, 3, 4} Explanation: When x = 1, 2x - 1 = 2(1) - 1 = 1 (odd) When x = 2, 2x - 1 = 2(2) - 1 = 3 (odd) When x = 3, 2x - 1 = 2(3) - 1 = 5 (odd) When...

C = {-8, 1} Explanation: By factoring or using the quadratic formula, we find that the roots of the equation are x=−8x=−8 and x=1x=1. So, C = {-8, 1}.
