Help neede in coordinate geometry!
here is the question :
If the pairs of lines [tex]x^2-2pxy-y^2[/tex] and [tex]x^2-2qxy-y^2[/tex] are such that each pair bisects the angle between the other pair , then pq equals ...??the answer somehow is -1. i think it uses the concept of homogenisation (if u ppl know what it is . searched the net but found not a single page on it ) . if u know this concept please explain it 2 me and how u come to this answer .
thanx in advance
