You can put this solution on YOUR website!
Use the vertex form,
\n" ); document.write( " $\"y=a%28x-12%29%5E2-8\"$
\n" ); document.write( "Then use either point to solve for a.
\n" ); document.write( " $\"0=a%2810-12%29%5E2-8\"$
\n" ); document.write( " $\"a%28-2%29%5E2=8\"$
\n" ); document.write( " $\"a=8%2F4\"$
\n" ); document.write( " $\"a=2\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"highlight%28y=2%28x-12%29%5E2-8%29\"$ \n" ); document.write( "

\n" );
