\n" ); document.write( "The equation you show clearly has a root at x=1. The other roots are one irrational and a pair of complex roots.

\n" ); document.write( "I'm wondering, though, if the equation was supposed to be x^4-10x^2+9=0. That equation is easy to solve.

\n" ); document.write( "\"x%5E4-10x%5E2%2B9+=+0\"
\n" ); document.write( "\"%28x%5E2-9%29%28x%5E2-1%29+=+0\"
\n" ); document.write( "\"%28x%2B3%29%28x-3%29%28x%2B1%29%28x-1%29+=+0\"

\n" ); document.write( "The solutions are -3, 3, -1, and 1.
