Solution steps

One step at a time

y²25 −x²9 =1

Phương trình chuẩn Hyperbola

(y−k)²a² −(x−h)²b² =1 là phương trình chuẩn cho một hyperbol hướng lên trên-xuống dưới
với tâm (h, k), bán trục a và bán liên hợp-trục b.

Viết lại y²25 −x²9 =1 dưới dạng một phương trình hyperbol chuẩn

(y−0)²5² −(x−0)²3² =1

Do đó, thuộc tính Hyperbol là:

(h, k)=(0, 0), a=5, b=3
