Question 771658
Q:
Sketch {{{4x^2+4y^2=4y-8x-5}}}
------------------------------------------------------------------------
A:
{{{(4x^2 + 8x) + (4y^2 - 4y) = -5}}}
{{{4(x^2 + 2x) + 4(y^2 - y) = -5}}}
{{{4(x^2 + 2x + 1) + 4(y^2 - y + 1/4) = -5 + 4 + 1}}}
{{{4(x + 1)^2 + 4(y - 1/2)^2 = 0}}}
{{{(x+1)^2 + (y-1/2)^2 = 0}}}
Therefore, the graph is point (-1,1/2).
