(s+t)(s^2-st+t^2)\r
\n" ); document.write( "\n" ); document.write( "We multiply s by every member of the trinomial(s^2-st+t^2), multiply t by every member of the same trinomial(s^2-st+t^2) and then we finally combine like terms.\r
\n" ); document.write( "\n" ); document.write( "s times s^2 = s^3\r
\n" ); document.write( "\n" ); document.write( "s times -st = -s^2t\r
\n" ); document.write( "\n" ); document.write( "s times t^2 = st^2\r
\n" ); document.write( "\n" ); document.write( "===================\r
\n" ); document.write( "\n" ); document.write( "We now do the same thing with t.\r
\n" ); document.write( "\n" ); document.write( "t times s^2 = s^2t\r
\n" ); document.write( "\n" ); document.write( "t times -st = -st^2\r
\n" ); document.write( "\n" ); document.write( "t times t^2 = t^3\r
\n" ); document.write( "\n" ); document.write( "===================\r
\n" ); document.write( "\n" ); document.write( "We now combine everything:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "s^3 -s^2t + st^2 + s^2t -st^2 + t^3 = \r
\n" ); document.write( "\n" ); document.write( "s^3 + t^3 is the final answer.\r
