Complete the square,
\n" ); document.write( " $\"f%28x%29=-3x%5E2%2B2x%2B5\"$
\n" ); document.write( " $\"f%28x%29=-3%28x%5E2-%282%2F3%29x%29%2B5\"$
\n" ); document.write( " $\"f%28x%29=-3%28x%5E2-%282%2F3%29x%2B1%2F9%29%2B5%2B3%2F9\"$
\n" ); document.write( " $\"f%28x%29=-3%28x-1%2F3%29%5E2%2B15%2F3%2B1%2F3\"$
\n" ); document.write( " $\"f%28x%29=-3%28x-1%2F3%29%5E2%2B16%2F3\"$
\n" ); document.write( "Now the equation is in vertex form,
\n" ); document.write( "( $\"h\"$ , $\"k\"$ )=( $\"1%2F3\"$ , $\"16%2F3\"$ )\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
