Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with stepbystep explanations, just like a math tutorThe complex conjugate of x i y is x − i y, so we would conventionally say the complex conjugate of − 3 2 i is − 3 − 2 i Note that the convention is for the i to come after a numeric constant but before a variable $\begingroup$ There is a standard proof that there are only the obvious solutions I can write it down if you cannot find it I may have sketched the proof for MSE in the past, but searching is too complicated The proof uses the factorization $(x\sqrt{2})(x\sqrt{2})$, and the fact that the integers of $\mathbb{Q}(\sqrt{2})$ have unique factorization
