Homework Statement
Hi everyone.
I'm studying a problem and I need to prove that I have a basis. I tryed a proof and to achieve it I need to show that :
if k divides a*b and also divides a2 +2*b2 Then k divides both a and b.
Homework Equations
I'm not sure what I'm asserting is true but if it was, then it would be great for me ( cause my proof would be finished).
I first thought that if k divided a sum then it divided every term of that sum but I understood it was wrong (the other way is correct).
I'm taking any idea!
