Divide the entire equation by .1
\n" ); document.write( "\"x%5E2+-+2x+-+9+=+0\"
\n" ); document.write( "Move the 9 to the other side
\n" ); document.write( "\"x%5E2+-+2x+=+9\"
\n" ); document.write( "Take \"1%2F2\" of the x coefficient and square it: \"%28%281%2F2%29b%29%5E2\"
\n" ); document.write( "...
\n" ); document.write( "b came from \"ax%5E2%2Bbx%2Bc=0\"
\n" ); document.write( "...
\n" ); document.write( "\"%281%2F2%292+=+1%5E2+=+1\"
\n" ); document.write( "Add 1 to both sides

\n" ); document.write( "\"%28x-1%29%5E2+=+10\"

\n" ); document.write( "\"sqrt%28x-1%29%5E2\" = +/- \"sqrt%2810%29\"
