If `6a^2-3b^2-c^2+7ab-ac+4bc=0` then the family of lines `ax+by+c=0,|a|+|b| != 0` can be concurrent at concurrent (A) (-2,3) (B) (3,-1) (C) (2,3) (D) (-3,1)

2a+b+2c=0(a,b,c in R), then the family of lines ax+by+c=0 is concurrent at

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

If 25a^2 + 16b^2 – 40ab – c^2 = 0 , then the family of straight line 2ax + by + c = 0 is concurrent at

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

If 4a^(2)+9b^(2)-c^(2)+12ab=0 then the family of straight lines ax+by+c=0 is concurrent at : (A)(-3,2) or (2,3)(B)(-2,3) or (2,-3)(C)(3,2) or (-3,-2)(D)(2,3) or (-2,-3)

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 the straight lines x+y-2-0,2x-y+1=0 and a x+b y-c=0 are concurrent, then the family of lines 2a x+3b y+c=0(a , b , c) are nonzero) is concurrent at (a) (2,3) (b) (1/2,1/3) (c) (-1/6,-5/9) (d) (2/3,-7/5)

If 6a^(2)+12b^(2)+2c^(2)+17ab-10bc-7ac=0 then all the lines represented by ax+by+c=0 are concurrent at the point
