Hence, if x 2 = y 2, it is true that x = ± y The reverse is immediate Another approach is to note that x 2 − y 2 = 0 as a polynomial in x over a field (think y as a constant in that field) has at most 2 roots (counting multiplicities) because it has degree 2 This basic fact about polynomials follows from the fact that some w being a rootX(x;y) = 4x 2y 2 and f y(x;y) = 2y 2x 2 Setting these partial derivatives equal to zero, we have the system 4x 2y 2 = 0;It evaluates as 2 separate conditions, and checks if both are true x == y z Check the Python documentation for a list of what is considered False in Python (However, interesting to note that, as opposed to other languages, the following if 3 < x < 6 is equivalent to if x > 3 and x < 6 )
