Algebra.Com's Answer #53545 by galactus(183)![]() ![]() You can put this solution on YOUR website! Start by finding the factors of the constant 4. They are +/-[1,2,4]\r \n" ); document.write( "\n" ); document.write( "So, divide the cubic by (x-1),(x+1),(x-2),(x+2),(x-4),(x+4). Upon division, does any of these cause the cubic to reduce to a quadratic?. \n" ); document.write( "Yes, (x-2) and (x-1).\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So, x-2 is a factor.\r \n" ); document.write( "\n" ); document.write( "Next, factor the resulting quadratic. That's easy.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So, the factored form of the cubic is \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
