If `4a^(2)+9b^(2)-c^(2)+12ab=0`, then the set of lines `ax+by+c=0` pass through the fixed point

If 3a+2b+4c=0 then the lines ax+by+c=0 pass through the fixed point

If 3a+2b+4c=0 then the lines ax+by+c=0 pass through the fixed point

If a+b+c=0 then the line 3ax+by+2c=0 passes through the fixed point

If a+b+c=0 the straight line 2ax+3by+4c=0 passes through the fixed point

If a, b, c are in A.P, the lines ax+by+c=0 pass through the fixed point

If 4a^(2)+c^(2)=b^(2)-4ac, then the variable line ax+by+c=0 always passes through two fixed points.The coordinates of the fixed points can be (-2,-1) (b) (2,-1)(-2,1) (d) (2,1)

Let a,b,c varepsilon R and satisfying (c-3b)^(2)+a^(2)-6ab+2ac=0, then the variable line ax+by+c=0 passes through a fixed point whose coordinates are

If 16a^(2)-40ab+25b^(2)-c^(2)=0 and the line ax+by+c=0 passes through a fixed point whose coordinate is
