\n" );
document.write( "y=(x+7)^2 + 13
\n" );
document.write( "y = x^2 + 14x + 49 +13
\n" );
document.write( "y = x^2 + 14x + 62
\n" );
document.write( "Check by completing the square
\n" );
document.write( "y = ax^2 + bx + c   ⇒ y = a(x -(-b/2a)^2) - a(-b/2a)^2 + c
\n" );
document.write( "y = (x+7)^2 -49 + 62
\n" );
document.write( "y = (x+7)^2 +13 \n" );
document.write( "

\n" );
