Solving z−2iz−6i=1⇒y=4 .....(1)
(where z=x+iy)
Now solving z+2iz−8+2i=53
⇒x2+y2−25x+4y+104=0 .....(2)
Solving (1) & (2) ⇒z=17+4i & 8+4i
⇒∑∣z∣2=(17)2+(4)2+(8)2+(4)2=385
Let S={z∈C:z−2iz−6i=1 and z+2iz−8+2i=53}.
Then z∈ s∑∣z∣2 is equal to

Let the image of parabola $x^{2}=4 y$, in the line $x-y=1$ be $(y+a)^{2}=b(x-c)$, $a, b, c \in \mathrm{~N}$. Then $a+b+c$ is equal to
The distance between the points (3, 4) and (6, 8) is:
If the chord joining the points $\mathrm{P}_{1}\left(x_{1}, y_{1}\right)$ and $\mathrm{P}_{2}\left(x_{2}, y_{2}\right)$ on the parabola $y^{2}=12 x$ subtends a right angle at the vertex of the parabola, then $x_{1} x_{2}-y_{1} y_{2}$ is equal to
The distance between the parallel lines 3x + 4y - 7 = 0 and 3x + 4y + 8 = 0 is:
Let a point $A$ lie between the parallel lines $L_{1}$ and $L_{2}$ such that its distances from $L_{1}$ and $L_{2}$ are 6 and 3 units, respectively. Then the area (in sq. units) of the equilateral triangle $A B C$, where the points $B$ and C lie on the lines $\mathrm{L}_{1}$ and $\mathrm{L}_{2}$, respectively, is :
