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( "\"%28x%5E3-5x%5E2%2B8x-4%29%2F%28x-2%29=x%5E2-3x%2B2\"\r
\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( "\"x%5E2-3x%2B2=%28x-2%29%28x-1%29\"\r
\n" ); document.write( "\n" ); document.write( "So, the factored form of the cubic is \"%28x-2%29%5E2%28x-1%29\"\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
