parabola x^2-2x+8y+25=0
8y = x^2-2x+25
completing the square on the left side of the EQ
8y = (x-1)^2 -1 + 25
8y = (x-1)^2 + 24
y = (1/8)(x-1)^2 + 3 Vertex(1,3)
Axis: x= 1

Need to Know____________
The vertex form of a Parabola opening up(a>0) or down(a<0),

where(h,k) is the vertex and x = h is the Line of Symmetry ,
the focus is (h,k + p), With Directrix y = (k - p), a = 1/(4p)
