\n" ); document.write( "Rewrite:
\n" ); document.write( "y = (x-(x+i))(x-(x-i))
\n" ); document.write( "------------------
\n" ); document.write( "y = ((x-4)-i)((x-4)+i)
\n" ); document.write( "--
\n" ); document.write( "Notice this has the form (a-b)(a+b)
\n" ); document.write( "---
\n" ); document.write( "y = [(x-4)^2 - (i)^2]
\n" ); document.write( "---
\n" ); document.write( "y = [x^2-8x+16+1]
\n" ); document.write( "---
\n" ); document.write( "y = x^2-8x+17
