Question

The position of the point (1, 2) relative to the ellipse 2x² + 7y² = 20 is 

A. outside the ellipse 

B. inside the ellipse but not at the focus 

C. on the ellipse 

D. at the focus

Answer 1

Correct option A. outside the ellipse

Explanation:

2x² + 7y² – 20 = 0

Put x = 1, y = 2

2 + 28 – 20 = 10 > 0

∴ (1, 2) lies outside the ellipse.
