You don't have to do what the other person did. It's TOTALLY UNNECESSARY!

document.write( "Maximum height occurs at: 
\n" );
document.write( "With t = 2.5, maximum height of ball, or:  
\n" );
document.write( "To find the time it takes for the ball to hit the ground, we set h(t) = 0. We then get: 
\n" );
document.write( "0 = (t - 6)(t + 1)
\n" );
document.write( "0 = t - 6                OR                 0 = t + 1
\n" );
document.write( "Time it takes to hit the ground, or:         OR            t = - 1 (ignore)
\n" );
document.write( "In other words, you don't have to COMPLETE the SQUARE, and you certainly DON'T have to use the quadratic equation formula! Unless you want to!! \n" );
document.write( "

\n" );
