You can put this solution on YOUR website!
A quadratic factor of f(x) is $\"%28x-%281-i%29%29%28x-%281%2Bi%29%29=%28%28x-1%29%2Bi%29%28%28x-1%29-i%29=x%5E2-2x%2B1-i%5E2\"$
\n" ); document.write( " $\"x%5E2-2x%2B2\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "What happens when you divide $\"12x%5E4-23x%5E3%2B21x%5E2%2B4x-2\"$ by $\"x%5E2-2x%2B2\"$ ? Remainder should be 0. \n" ); document.write( "
