document.write( "y=-4.9t^2+51t+1.3\r\n" );
document.write( "\r\n" );
document.write( "you are trying to find the maximum height\r\n" );
document.write( "\r\n" );
document.write( "It makes absolutely no sense completing the square to determine the vertex. \r\n" );
document.write( "\r\n" );
document.write( "All you need to do is apply the formula for the x-coordinate of the vertex/axis of symmetry (\"matrix%281%2C3%2C+t%2C+%22=%22%2C+%28-+b%29%2F%282a%29%29\"). \r\n" );
document.write( "Then, substitute that \"t\" value into the given quadratic equation to get the y-coordinate of the vertex,\r\n" );
document.write( "which happens to be the MAXIMUM height. This you also need.\r\n" );
document.write( "\r\n" );
document.write( "Then again, you may be learning how to complete the square and this is an exercise to familiarize yourself with\r\n" );
document.write( "it and go through the process.
