We say that a point p = (x, y) in r2 is rational if both x and y are rational. more precisely, p is rational if p = (x, y) ∈ q2. an equation f(x, y) = 0 is said to have a rational point if there exists x0, y0 ∈ q such that f(x0, y0) = 0. for example, the curve x2+y2−1=0 has rational point (x0,y0)=(1,0). show that the curve x2 + y2 − 3 = 0 has no rational points
