\n" );
document.write( " 9x^2 - 9x + 1  Note using ^ (uppercase '6') to indicate squared term
\n" );

\n" );
document.write( " 9(x^2 - x) +1
\n" );
document.write( " 9[(x- 1/2)^2 -1/4] + 1
\n" );
document.write( "  9(x- 1/2)^2 - 9/4 + 1
\n" );
document.write( "  9(x- 1/2)^2 - 5/4  in the form a(x+b) + c where a = 9, b = -1/2 and c = -5/4
