10-2. Parabola, Ellipse, Hyperbola
normal
The number of real tangents that can be drawn to the ellipse $3x^2 + 5y^2 = 32$ passing through $(3, 5)$ is
A
$0$
B
$1$
C
$2$
D
infinite
Solution
Since $3(3)^2 + 5(5)^2 – 32 > 0$ . So the given point lies outside the ellipse. Hence, two real tangents can be drawn from the point to the ellipse
