document.write( "Standard form of a parabolic equation: 
\n" );
document.write( "The x-coordinate of the vertex occurs at: . This is also the axis of symmetry.
\n" );
document.write( "The y-coordinate of the vertex occurs at: , where x is the value of the x-coordinate of the vertex
\n" );
document.write( "The x intercepts, or roots occur at the solutions to: 
\n" );
document.write( "The y-intercept occurs at . Looking at the equation, it should be: \r
\n" );
document.write( "\n" );
document.write( "**FYI
\n" );
document.write( "If you intend to create the vertex form of the equation, then you'd need to divide through by 4.
\n" );
document.write( "Otherwise, that's too much work. \n" );
document.write( "

\n" );
