$\"+x%5E2+=+9x+%2B+20+\"$
\n" ); document.write( "Subtract $\"+9x+\"$ from both sides
\n" ); document.write( " $\"+x%5E2+-+9x+=+20+\"$
\n" ); document.write( "Complete the square. Take 1/2 of the $\"+-9+\"$ ,
\n" ); document.write( "square it, and add it to both sides
\n" ); document.write( " $\"+x%5E2+-+9x+%2B+%28+-9%2F2+%29%5E2+=+20+%2B+%28+-9%2F2+%29%5E2+\"$
\n" ); document.write( " $\"+x%5E2+-+9x+%2B+20.25+=+20+%2B+20.25+\"$
\n" ); document.write( " $\"+%28+x+-+4.5+%29%5E2+=+40.25+\"$
\n" ); document.write( "Take the square root of both sides
\n" ); document.write( " $\"+x+-+4.5+=+sqrt%28+40.25+%29+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+x+-+4.5+=+-sqrt%28+40.25+%29+\"$
\n" ); document.write( "The factors are
