You can put this solution on YOUR website!
Let's do the last one first
\n" ); document.write( "we want factors of 12 that add up to 4 or have a difference of 4
\n" ); document.write( "since both -4y qnd -12 are negative the difference has to be 4
\n" ); document.write( "If they were both negative then the 12 would be +12
\n" ); document.write( "1,12
\n" ); document.write( "6,2
\n" ); document.write( "3,4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "6 and 2
\n" ); document.write( "so the 6 is - and the 2 is plus
\n" ); document.write( "(x-6)(x+2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(y-6) (y+2)\r
\n" ); document.write( "\n" ); document.write( "the first one is right
\n" ); document.write( "You aren't even close on the second one
\n" ); document.write( "-1*5 doesn't=6
\n" ); document.write( "we need factors of 6 that add up to 5
\n" ); document.write( "both positive\r
\n" ); document.write( "\n" ); document.write( "BTW the website rules say
\n" ); document.write( " one problem per submission - one rule broken
\n" ); document.write( "no similar problems- two rules broken
\n" ); document.write( "also a limit of 4 submission/problems daily
\n" ); document.write( "
\n" ); document.write( "
\n" );
