If `4a+5b+c=0` then the set of lines `ax+by+c=0` are concurrent at the point

If a^2-b^2-c^2-2ab=0 , then the family of lines ax+by+c=0 are concurrent at the points

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

If a^2+b^2-c^2-2ab = 0 , then the family of straight lines ax + by + c = 0 is concurrent at the points

If a,b,c are in A.P then the lines represented by ax+by+c=0 are concurrent at the point

The set of lines ax+by+c=0, where 3a+2b+4c=0, is concurrent at the point:

The set of lines ax+by+c=0 , where 3a+2b+4c=0 is concurrent at the point…

If a^(2)+9b^(2)-4c^(2)=6ab, then the family of lines ax+by+c=0 are concurrent at:

If 6a^2-3b^2-c^2+7ab-ac+4bc=0 , then the family of lines ax+by+c=0 is concurrent at

(i) If a, b, c, are in A.P. then show that ax….+….by +c=0 passes through a fixed point. Find then fixed point. (ii) If 9a^(2)+16b^(2)-24ab-25c^(2)=0, then the family of straight lines ax+by+0 is concurrent at the point whose co-ordinates are given by "________" (iii) If 3a+4b-5c=0, then the family of straight lines ax+by+c=0 passes through a fixed point. Find the coordinates of the point.
