$\"y=8x%5E2%2B16x\"$ To find the roots solve y=0\r
\n" ); document.write( "\n" ); document.write( " $\"8x%28x%2B2%29=0\"$ the roots are x=0 or x=-2\r
\n" ); document.write( "\n" ); document.write( "The vertex is the point (x,y) where $\"x=-b%2F2a\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=-16%2F16\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=-1\"$ ,and \r
\n" ); document.write( "\n" ); document.write( " $\"y=8%28-1%29%5E2%2B16%28-1%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=-8\"$ .\r
\n" ); document.write( "
