Let PQR be right angled isosceles triangle, right
angled at P(2,1). If the equation of the line QR is
2x + y = 3, then the equation representing the pair of lines PQ and PR is
angled at P(2,1). If the equation of the line QR is
2x + y = 3, then the equation representing the pair of lines PQ and PR is
- 3x2 – 3y2 + 8xy + 20x + 10y + 25 = 0
- 3x2 – 3y2 + 8xy – 20x – 10y + 25 = 0
- 3x2 – 3y2 + 8xy + 10x + 15y + 20 = 0
- 3x2 – 3y2 + 8xy – 10x – 15y – 20 = 0
Answer
(B) 3 x 2 – 3 y 2 + 8 xy – 20 x – 10 y + 25 = 0
