You can put this solution on YOUR website!
$\"y=2%28x-5%29%5E2%2B63\"$
\n" ); document.write( "I'm going to put this into standard form first:
\n" ); document.write( " $\"y=2%28x%5E2-10x%2B25%29%2B63\"$
\n" ); document.write( " $\"y=2x%5E2-20%2B50%2B63\"$
\n" ); document.write( " $\"y=2x%5E2-20%2B113\"$
\n" ); document.write( "-----------------
\n" ); document.write( "Axis of symmetry from standard form equation is given as
\n" ); document.write( " $\"x=-b%2F2a\"$
\n" ); document.write( " $\"x=20%2F4\"$
\n" ); document.write( " $\"highlight%28x=5%29\"$
\n" ); document.write( "-----------------
\n" ); document.write( "Note that you could also read it off directly from the vertex form:
\n" ); document.write( " $\"x=-h\"$ where h is -5.
