Convert the quadratic equation to vertex form.
\n" ); document.write( "The maximum occurs at the vertex.
\n" ); document.write( " $\"H%28t%29=-2t%5E2%2B20t%2B10\"$
\n" ); document.write( " $\"H%28t%29=-2%28t%5E2-10t%29%2B10\"$
\n" ); document.write( " $\"H%28t%29=-2%28t%5E2-10t%2B25%29%2B10%2B2%2825%29\"$
\n" ); document.write( " $\"H%28t%29=-2%28t-5%29%5E2%2B10%2B50\"$
\n" ); document.write( " $\"H%28t%29=-2%28t-5%29%5E2%2B60\"$
