\n" ); document.write( "Use the FOIL method for the first expression (First Outer Inner Last)
\n" ); document.write( "\"%285%2B3j%29%283-j%29-%283%2Bj%29=5%2A3%2B5%28-j%29%2B%283j%293%2B%283j%29%28-j%29-3-j\" FOIL and distributive property.
\n" ); document.write( "Remember that \"j%5E2=-1\"
\n" ); document.write( "\"%285%2B3j%29%283-j%29-%283%2Bj%29=15-5j%2B9j%2B3-3-j\" \r
\n" ); document.write( "\n" ); document.write( "\"%285%2B3j%29%283-j%29-%283%2Bj%29=15%2B3-3%2Bj%28-5%2B9-1%29\" Group like terms.
\n" ); document.write( "\"%285%2B3j%29%283-j%29-%283%2Bj%29=15%2Bj3\" Final answer.
