Question

Use euclid's division lemma to show that the square of any odd integer is the form of 4q - 1 for some integer q​

Answer 1

Answer:

4q + 1 is an odd number. 4q + 2 i.e., 2(2q + 1) which is also an even number. ∴ (4q + 2) + 1 = 4q + 3 is an odd number. Thus, we can say that any odd integer can be written in the form 4q + 1 or 4q + 3 where q is some integer
