Question

If lines represented by equation p x 2 - q y 2 = 0 are distinct then, p q > 0, p q 0, p q = 0, p + q = 0

MARKS App · Accepted Answer

p x 2 - q y 2 = 0 Comparing with standard homogeneous equation we get, a = p , b = - q , h = 0 Lines are real and distinct if h 2 - a b > 0 ⇒ 0 + p q > 0 p q > 0
