Answer» How many of the following statements are correct ___ 1. A conic with eccentricity equal to one is called a parabola 2. If $a x^{2} + 2 h x y + b y^{2} + 2 g x + 2 f y + c = 0$ represents a parabola, then $a b c + 2 f g h - a f^{2} - b g^{2} - c h^{2} \neq 0 a n d h^{2} = a b$

Answer»

How many of the following statements are correct ___

1. A conic with eccentricity equal to one is called a parabola

2. If $a x^{2} + 2 h x y + b y^{2} + 2 g x + 2 f y + c = 0$ represents a parabola, then

$a b c + 2 f g h - a f^{2} - b g^{2} - c h^{2} \neq 0 a n d h^{2} = a b$
