Question

What will be the equation of the chord of contact of tangents drawn from (3, 2) to the ellipse $x^{2} + 4y^{2} = 9$

• A. $3x + 8y = 9$
• B. $3x + 8y = 25$
• C. $3x + 4y = 9$
• D. $3x + 8y + 9 = 0$

Answer 1

Answer: (A)

$3x + 8y = 9$

Answer 2

The required equation is $T = 0$i.e. ,$3x + 4(2y) - 9 = 0$or $3x + 8y = 9$
