FYI: 4 is the GCF (greatest common factor) of the equation, NOT the LCM
\n" );
document.write( "When you divided by 4, you were supposed to get: 
\n" );
document.write( "Do you see how this was done? You should've divided BOTH sides by 4, not just the left side
\n" );
document.write( "Now, 4 = 4, and what's in the parentheses are set equal to each other
\n" );
document.write( "So, we have: 4 = 4 (TRUE), and . The  quadratic equation is then factored and solved for x to get roots of 2 and 9. \n" );
