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 rootExpand (x−y)(x2 xyy2) ( x y) ( x 2 x y y 2) by multiplying each term in the first expression by each term in the second expression Simplify terms Tap for more steps Simplify each term Tap for more steps Multiply x x by x 2 x 2 by adding the exponents Tap for more steps Multiply x x by x 2 x 2Since y^2 = x − 2 is a relation (has more than 1 yvalue for each xvalue) and not a function (which has a maximum of 1 yvalue for each xvalue), we need to split it into 2 separate functions and graph them together So the first one will be y 1 = √ (x − 2) and the second one is y 2 = −√ (x − 2)
