The roots are
\n" ); document.write( " $\"+x+=+1+\"$
\n" ); document.write( " $\"+x+=+-6+\"$
\n" ); document.write( "----------
\n" ); document.write( "Now rewrite these as
\n" ); document.write( " $\"+x+-+1+=+0+\"$
\n" ); document.write( " $\"+x+%2B+6+=+0+\"$
\n" ); document.write( "------------
\n" ); document.write( "Now express the product:
\n" ); document.write( " $\"+%28+x-1+%29%2A%28+x+%2B+6+%29+=+0+\"$
\n" ); document.write( " $\"+x%5E2+-x+%2B+6x+-+6++=+0+\"$
\n" ); document.write( " $\"+x%5E2+%2B+5x+-+6+=+0+\"$
\n" ); document.write( "The function is:
\n" ); document.write( " $\"+f%28x%29+=+x%5E2+%2B+5x+-+6+\"$
\n" ); document.write( "Here's a plot:
