find the center and radius of the following circle:
\n" ); document.write( "x^2+y^2+4x-6y-23=0
\n" ); document.write( "--
\n" ); document.write( "I just did this one.
\n" ); document.write( "========================================
\n" ); document.write( "write the equation of the circle with the given center and radius: CENTER:(-4,0)r=2
\n" ); document.write( "\"%28x%2B4%29%5E2+%2B+%28y-0%29%5E2+=+2%5E2\"
\n" ); document.write( "\"%28x%2B4%29%5E2+%2B+y%5E2+=+4\"
\n" ); document.write( "
