The condition that the parabolas `y^2=4c(x-d)` and `y^2=4ax` have a common normal other than X-axis `(agt0,cgt0)` is

Obtained the condition that the parabola y^(2)=4b(x-c)andy^(2)=4ax have a common normal other than x-axis (agtbgt0) .

If the parabolas y^(2)=4ax and y^(2)=4c(x-b) have a common normal other than the x -axis (a,b,c being distinct positive real numbers),then prove that (b)/(a-c)>2

If the parabolas y^2=4a x and y^2=4c(x-b) have a common normal other than the x-axis (a , b , c being distinct positive real numbers), then prove that b/(a-c)> 2.

If the parabolas y^2=4a x and y^2=4c(x-b) have a common normal other than the x-axis (a , b , c being distinct positive real numbers), then prove that b/(a-c)> 2.

If the parabolas y^2=4a x and y^2=4c(x-b) have a common normal other than the x-axis (a , b , c being distinct positive real numbers), then prove that b/(a-c)> 2.

If the parabolas y^2=4a x and y^2=4c(x-b) have a common normal other than the x-axis (a , b , c being distinct positive real numbers), then prove that b/(a-c)> 2.

If the two parabolas y^2 = 4x and y^2 = (x-k) have a common normal other than x-axis, then value of k can be (A) 1 (B) 2 (C) 3 (D) 4

If a,b,c are distincl positive real numbers such that the parabola y^(2) = 4ax and y^(2) = 4c ( x - b) will have a common normal, then prove that (b)/(a-c) gt 2

If a,b,c are distincl positive real numbers such that the parabola y^(2) = 4ax and y^(2) = 4c ( x - b) will have a common normal, then prove that (b)/(a-c) gt 2

If the parabols y^(2) = 4kx (k gt 0) and y^(2) = 4 (x-1) do not have a common normal other than the axis of parabola, then k in
