You could use the quadratic equation formula, but I prefer the method below:
\n" );
document.write( "You may remember that: 
\n" );
document.write( "Let's call the other root: R2. We can see from the quadratic equation that: a = 1; b = - 3, and c = k - 2 
\n" );
document.write( "We then get: 
\n" );
document.write( "We also get: 
\n" );
document.write( "==============================================================================================
\n" );
document.write( "AND an even easier method is the REMAINDER THEOREM method used by TUTOR @Rothauserc, which should actually be:
\n" );
document.write( " \n" );

\n" );
