The standard form for an ellipse is \"x%5E2%2Fa%5E2+%2B+y%5E2%2Fb%5E2+=+1\"
\n" ); document.write( "The major axis goes from (-a,a).
\n" ); document.write( "Since 25=5^2, the x intercepts are x=-5, x=5.
\n" ); document.write( "Another way to see this is to set y=0 in the equation for the ellipse.
\n" ); document.write( "Then we have \"x%5E2%2F25+=+1\" -> \"x%5E2+=+25\". The two solutions are -5,5.
\n" ); document.write( "
\n" );
