(x+h)(x+h)(x+h)= ?
\n" ); document.write( "= (x^2+2hx+h^2)(x+h)\r
\n" ); document.write( "\n" ); document.write( "= (x^2+2hx+h^2)x + (x^2+2hx+h^2)h\r
\n" ); document.write( "\n" ); document.write( "= x^3+2hx^2+h^2x + hx^2+2h^2x + h^3\r
\n" ); document.write( "\n" ); document.write( "= x^3 + (2x+h)x^2 + (h^2+2h^2)x + h^3\r
\n" ); document.write( "\n" ); document.write( "= x^3 + (3h)x^2 + (3h^2)x + h^3
