Use the FOIL method to work out the left hand side.

\n" ); document.write( "\"%283Y-1%29%282Y%2BK%29=6Y%5E2%2B%283K%2B2%29Y-K\"
\n" ); document.write( "Now compare it to the right hand side.
\n" ); document.write( "1.\"A=6\"
\n" ); document.write( "2.\"3K%2B2=B\"
\n" ); document.write( "3.\"-K=-5\"
\n" ); document.write( "From eq. 3,
\n" ); document.write( "\"K=5\"
\n" ); document.write( "Use that in eq. 2,
\n" ); document.write( "\"3%285%29%2B2=B\"
\n" ); document.write( "\"B=17\"
\n" ); document.write( "So then,
