Through the left focus F1 of hyperbola X & sup2; - 3 / Y & sup2; = 1, make the chord AB with slope 2, find (1), the length of line AB; (2), set point F2 as the right focus

Through the left focus F1 of hyperbola X & sup2; - 3 / Y & sup2; = 1, make the chord AB with slope 2, find (1), the length of line AB; (2), set point F2 as the right focus

The equation of AB is y = 2 (x + 2), and the equation of AB is y = 2 (x + 2), and y = 2 (x + 2) (x + 2) is substituted into x \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\5 (25
