You can put this solution on YOUR website!
We can see that x = 1 is a solution of
\n" ); document.write( "x^3 + x - 2 = 0
\n" ); document.write( "but if we factor that expression by x - 1, we get
\n" ); document.write( "(x - 1)(x^2 + x + 2) = 0
\n" ); document.write( "and the second polynomial is not factorable...you have to use the quadratic...
\n" ); document.write( "so x = 1 and
\n" ); document.write( "x = (-1 ± i*sqrt(7)) / 2 \n" ); document.write( "
\n" );
