First solve q(x,y,z)= 2 mod 8, then use Hensel's Lemma to lift to a solution in Z2. When working with quadratic forms in characteristic 2, usually it helps to work mod 8. A good reason ...

Expand (x−y−z)(x−y−z) (x - y - z) (x - y - z) by multiplying each term in the first expression by each term in the second expression. x⋅x+x(−y)+x(−z)− yx−y(−y)−y(−z)− zx−z(−y)− z(−z) x ⋅ x + x (- …

2023年5月4日 · The expression to make a true equation: (xyz)² - 1 = (____) x (xyz - 1) is (xyz + 1) using difference of two squares. Considering two numbers a and b, the difference of their …

Define f(x, y, z) = √x2 + y2 + z2, which is what we want to minimize, with the constraint g(x, y, z) = xyz2 = 2. We get three equations (I'm using f as shorthand to avoid the messy root): We get y …

Find the shortest distance from the origin to the surface of $xyz^2=2$, i.e. minimize $f (x,y,z)=x^2+y^2+z^2$ subject to $xyz^2-2=0$ hence we obtain $L …
