1.	ax2+2hxy+by2=0 always represents a pair of straight lines passing through the origin. If Column 1 Column 2 a. h2>ab 1. Lines are coincident b. h2=ab 2. Lines are real and distinct c. h2<ab 3. Lines are imaginary with real point of intersection i.e. (0,0)
Answer» $a x^{2} + 2 h x y + b y^{2} = 0$ always represents a pair of straight lines passing through the origin. If Column 1 Column 2 a. $h^{2}$ >ab 1. Lines are coincident b. $h^{2}$ =ab 2. Lines are real and distinct c. $h^{2}$ <ab 3. Lines are imaginary with real point of intersection i.e. (0,0)

Answer»

$a x^{2} + 2 h x y + b y^{2} = 0$ always represents a pair of straight lines passing through the origin. If

Column 1 Column 2

a. $h^{2}$ >ab 1. Lines are coincident

b. $h^{2}$ =ab 2. Lines are real and distinct

c. $h^{2}$ <ab 3. Lines are imaginary with real point of intersection i.e. (0,0)
