To multiply, we can use FOIL with the first two items, but we must use distribution with the last.
\n" ); document.write( ".
\n" ); document.write( "To start,,,,(t+1)(2t-2)
\n" ); document.write( ".
\n" ); document.write( "First term,,,,(t)*(2t) = 2t^2
\n" ); document.write( "Outside terms,,,(t)*(-2) = -2t
\n" ); document.write( "Inside terms,,,,(1)*(2t) = 2t
\n" ); document.write( "Last terms,,,,,,(1)*(-2) = -2
\n" ); document.write( ".
\n" ); document.write( "we can combine the \"t\" terms,,,,-2t +2t =0
\n" ); document.write( ".
\n" ); document.write( "The result is (2t^2 -2 )
\n" ); document.write( ".
\n" ); document.write( "To complete the problem,,,,(t+4)*(2t^2 -2)
\n" ); document.write( ".
\n" ); document.write( "Since this is only 2x2 terms we could foil again, but let's use distribution, which is more general.
\n" ); document.write( ".
\n" ); document.write( "t*(2t^2-2) +4(2t^2-2)
\n" ); document.write( ".
\n" ); document.write( "2t^3 -2t +8t^2 -8
\n" ); document.write( ".
\n" ); document.write( "2t^3 +8t^2 - 2t -8,,,,,,final answer
\n" ); document.write( ".
\n" ); document.write( "check,,let x=3,,,both original and answer = 112,,,,,ok
\n" ); document.write( ".
