    -4x^2+y^2-8x+36 = 0 -4x^2-8x-4+y^2-12y+36+4=0 -4(x^2+2x+1) + (y-6)^2 = -4 (x+1)^2^2+(y-6)^2 = 1

    so its (x+1)^2+(y-6)^2=1 How do i get the center ? -1,6?

    ok, so how do i get vertices? now in standard form: (x+1)^2/1 - (y-6)^2/4=1

    thats what it gives me though. (x+1)^2/1 - (y-6)^2/4 how do i find the vertices?

    o yeah sorry I forgot something -4x^2+y^2-8x+36 = 0 -4x^2-8x-4+y^2-12y+36+4=0 -4(x^2+2x+1) + (y-6)^2 = -4 (x+1)^2+(y-6)^2/-4 = (x+1)^2-(y-6)^2/4=1
