You can put this solution on YOUR website!
convert (x^2+y^2+2x-10=0) into (x-h)^2+(y-k)^2=r^2 format
\n" ); document.write( "---------
\n" ); document.write( "You need to \"complete the square\" on the x terms and separately
\n" ); document.write( "on the y terms, as follows:\r
\n" ); document.write( "\n" ); document.write( "---------------
\n" ); document.write( "(x^2+2x+1) + (y^2) = 10+1
\n" ); document.write( "(x+1)^2 + (y-0)^2 = [sqrt(11)]^2
\n" ); document.write( "Center is at (-1,0)
\n" ); document.write( "Radius is sqrt(11)
\n" ); document.write( "Cheers,
