Using the rational root theorem, you'll find that 1 and - 3 are 2 of the roots. 
\n" );
document.write( "Therefore, 2 of its factors are: (x - 1) and (x + 3), which combine to give the factor: 
\n" );
document.write( "Dividing  by the factor:  () by long division or synthetic division results in the other factor: 
\n" );
document.write( " = . Thus, the other 2 roots are: 
\n" );
document.write( "Therefore, roots, or zeroes are:  \n" );
document.write( "

\n" );
