You can put this solution on YOUR website!
If $\"x=-i\"$ is a zero, then so is $\"x=i\"$
\n" ); document.write( " $\"f%28x%29=a%28x-1%29%28x-2%29%28x-i%29%28x%2Bi%29\"$
\n" ); document.write( " $\"f%280%29=a%28-1%29%28-2%29%28-i%29%28i%29=8\"$
\n" ); document.write( " $\"a%28-2%29%28-i%5E2%29=8\"$
\n" ); document.write( " $\"a=-4\"$
\n" ); document.write( " $\"f%28x%29=-4%28x-1%29%28x-2%29%28x-i%29%28x%2Bi%29\"$
\n" ); document.write( "However the leading coefficient is $\"-4\"$ .
