WebJul 22, 2012 · I was saying that I could see that it looks pretty obvious that if n divides a-b, it will divide a 2-b 2, but that I didn't know how to prove it. Using oay's hint about factorisation I've got a 2-b 2 =(a+b)(a-b) and since n divides a-b, n therefore divides a 2-b 2 but this is looking very different to the examples in the book. OK, after a pause to try again I think … WebTo make this equal to A, we want 2 a b = 1 and 14 a 2 + b 2 = 0. Thus b = 1 / ( 2 a) and 14 a 2 = − 1 / ( 4 a 2), or a 4 = − 1 / 56. Take a to be any of the four fourth roots of − 1 / 56, and you have a solution. I'm in the same problem, but I have a matrix A = ( 1 4).
