document.write( "Substitute (-2) in place of x in \r\n" );

document.write( "y = 2x^2 + 1\r\n" );

document.write( "y = 2(-2)^2 + 1\r\n" );
document.write( "\r\n" );
document.write( "Substitute (4) in place of (-2)^2 because -2 times itself gives +4\r\n" );
document.write( "\r\n" );
document.write( "y = 2(4) + 1\r\n" );
document.write( "\r\n" );
document.write( "Substitute 8 in place of 2(4) because 2 times 4 is 8\r\n" );
document.write( "\r\n" );
document.write( "y = 8 + 1\r\n" );
document.write( "\r\n" );
document.write( "Substitute 9 in place of 8 + 1 because 8 plus 1 is 9\r\n" );
