Algebra.Com's Answer #189586 by richwmiller(17219)![]() ![]() 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( " |
