\n" ); document.write( "It's not a question, it's an equation.
\n" ); document.write( "Graphing it is not solving it.
\n" ); document.write( "------
\n" ); document.write( "Graph the circle x^2+y^2-4x+2y-4=0
\n" ); document.write( " $\"x%5E2+%2B+4x+%2B+y%5E2+%2B+2y+=+4\"$
\n" ); document.write( "Complete the squares for x and y
\n" ); document.write( " $\"x%5E2+%2B+4x+%2B+4+%2B+y%5E2+%2B+2y+%2B+1+=+9\"$
\n" ); document.write( " $\"%28x%2B2%29%5E2+%2B+%28y+%2B+1%29%5E2+=+3%5E2\"$
\n" ); document.write( "The center is (-2,-1)
\n" ); document.write( "The radius = 3
