If a, c, b are in G.P then the line `ax + by + c= 0`

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

If a, b, c are in A. P., then st. line ax+by+c=0 will always pass through a fixed point whose co-ordinates are:

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

IF a,b,c are in A.P then the striaght line ax+by+c=0 will always pass through a fixed point. Find it.

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

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

If a,b, c are in G.P., then the equations ax^(2) + 2bx + c = 0 and dx^(2) + 2ex + f = 0 have common root if (d)/(a), (e)/(b), (f)/(c) are in

If a,b,c are in G.P., then the equations ax^2+2bx+c =0 and dx^2+2ex+f =0 have a common root if d/a,e/b,f/c are in

If a, b, c are in G.P. and the equation ax^(2) + 2bx + c = 0 and dx^(2) + 2ex + f = 0 have a common root, then show that (d)/(a), (e)/(b), (f)/(c ) are in A.P.
