\n" );
document.write( " a. Move the constant term to the right side of the equation:
\n" );
document.write( " x2 + 12x = 64

document.write( " c. Square the coefficient of the original x term and add it to both sides of the equation:
\n" );
document.write( "I am stuck here. I hope this is correct thus far.
