By shifting origin to `(-1,2)` the equation `y^2+8x - 4y + 12 = 0` changes as `Y^2 = 4aX` then `a=`

The origin is shifted to (1,2), the equation y^(2)-8x-4y+12=0 changes to Y^(2)+4aX=0 then a=

The origin is shifted to (1,2). The equation y^(2) - 8x-4y+12=0 changes to y^(2) = 4ax then a=

Origin is shifted to (1,2) then the equation y^(2)-8x-4y+12-0 changes as y^(2)=4ax .Then a=

If the equation y^(2) - 4x + 6y + 17 = 0 changed as y^(2) = 4ax then shifted origin is

The origin shifted to (-5,3) then the equation y^(2)-12x+6y+69=0 changes as y^(2)=4ax then a

If by shifting the origin to (1,2) the equation of the parabola y^(2)-4y+8x-4=0 becomes y^(2)=4ax, then a equal to

The equation 8x^2+12y^2-4x + 4y-1=0 represents
