<em>x</em> ² - 4<em>x</em> + <em>y</em> ² + 8<em>y</em> = -4
(<em>x</em> ² - 4<em>x</em> + 4) + (<em>y</em> ² + 8<em>y</em> + 16) = -4 + 4 + 16
(<em>x</em> - 2)² + (<em>y</em> + 4)² = 16
(<em>x</em> - 2)² + (<em>y</em> + 4)² = 4²
which is the equation of a circle centered at (2, -4) and with radius 4.
8+8+8 is that as repeated addition
