If 4a^(2)+9b^(2)-c^(2)-12ab=0 then family of straight lines ax+by+c=0 are concurrent at P and Q then values of P & Q are

If 2a^(2)-7ab-ac+3b^(2)-2bc-c^(2)=0 then the family of lines ax+by+c=0 are either concurrent at the point P(x_(1),y_(1)) or at the point Q(x_(2),y_(2)). Find the distance of the origin from the listance being measured parallel to the line 3x-4y=2.

If 16a^(2)+25b^(2)-c^(2)=40ab, then the family of lines ax+by+c=0 is concurrent at the point(s)
