Hi there,
\n" ); document.write( "the difference between -x^2+10x-3 and x^2+6x+5
\n" ); document.write( "(-x^2 + 10x - 3)-(x^ + 6x + 5)
\n" ); document.write( "-x^2 + 10x - 3 - x^2 - 6x - 5
\n" ); document.write( "=-2x^2 + 4x - 8
\n" ); document.write( ".............
\n" ); document.write( "add 5x^3-8x+1
\n" ); document.write( "5x^3 - 8x + 1 + (-2x^2 + 4x - 8)
\n" ); document.write( "5x^3 - 8x + 1 - 2x^2 + 4x - 8
\n" ); document.write( "=5x^3 - 2x^2 - 4x - 7
\n" ); document.write( "Hope this helps:-)
