(x-3)(x^6-2x^3+1)=0\r
\n" ); document.write( "\n" ); document.write( "(x-3)(x^3-1)^2 = 0
\n" ); document.write( "(x-3)(x-1)(x^2+x+1) = 0
\n" ); document.write( "------------
\n" ); document.write( "Roots of x^2+x+1:
\n" ); document.write( "x = [-1 +- sqrt(1-4*1*1)]/2\r
\n" ); document.write( "\n" ); document.write( "x = [-1 +- isqrt(3)]/2
\n" ); document.write( "====================
\n" ); document.write( "Ans: x=3 or x=1 or x = [-1 +- isqrt(3)]/2
\n" ); document.write( "====================
