How can we do the proposition for a-c? Name:MATH 140 Lecture 12 HomeworkSection:1. Show the following propositions using a proof by contradiction.(a) Proposition. Suppose n E Z. If n² is odd, then n is odd.(b) Proposition. If a, b = Z, then a² - 4b-20. (Hint: use the proposition that if a² iseven, then a is even.)(c) Proposition. There exist no integers a and b for which 18a + 6b = 1.
