帮我讲解一下这道题目---Example 2. Given hyperbola C₁: x²/4 - y²/12 = 1.
(1) If point M (3, t) is on hyperbola C₁, find the distance from point M to the right focus of hyperbola C₁;
(2) Find the standard equation of hyperbola C₂ that has the same asymptotes as hyperbola C₁ and passes through the point (-3, 2√6).
