What is the vertex of function $\"y=-x%5E2-5x-2\"$ ?
\n" ); document.write( "--
\n" ); document.write( " $\"y=-%28x%5E2%2B5x%29-2\"$ factor a -1 from the first two terms\r
\n" ); document.write( "\n" ); document.write( " $\"y=-%28x%5E2%2B5x%2B25%2F4-25%2F4%29-2\"$ add and subtract 25/4 to complete the square
\n" ); document.write( " $\"y=-%28x%2B5%2F2%29%5E2%2B25%2F4-2\"$
\n" ); document.write( " $\"y=+-%28x%2B5%2F2%29%5E2%2B25%2F4-8%2F4=-%28x%2B5%2F2%29%5E2%2B17%2F4\"$
