x(x+2)=4(x+x+2)-1
\n" ); document.write( "x^2+2x=4(2x+2)-1
\n" ); document.write( "x^2+2x=8x+8-1
\n" ); document.write( "x^2+2x-8x-8+1=0
\n" ); document.write( "x^2-6x-7=0
\n" ); document.write( "(x-7)(x+1)=0
\n" ); document.write( "x-7=0
\n" ); document.write( "x=7 for the smaller integer.
\n" ); document.write( "7=2=9 for the larger integer.
\n" ); document.write( "Proof:
\n" ); document.write( "7*9=4(7+9)-1
\n" ); document.write( "63=4*16-1
