Factor completely:
\n" ); document.write( "x^2 - 2x + y^2 + 2y - 2xy - 15
\n" ); document.write( "-------------------------
\n" ); document.write( "Rearrange:
\n" ); document.write( "x^2-2xy+y^2 -2(x-y) - 15
\n" ); document.write( "---------------------
\n" ); document.write( "(x-y)^2 -2(x-y) - 15
\n" ); document.write( "This is a quadratic with variable (x-y)
\n" ); document.write( "Factor:
\n" ); document.write( "[(x-y)-5][(x-y)+3]
\n" ); document.write( "=====================
