Let y = 0 and solve for x:
\n" ); document.write( " $\"9x%5E2+%2B+4%280%5E2%29+=+36\"$
\n" ); document.write( " $\"9x%5E2++=+36\"$ , divide both sides by 9
\n" ); document.write( " $\"x%5E2+=+4\"$
\n" ); document.write( "x = ą2
\n" ); document.write( "The x-intercepts are 2 and -2. \n" ); document.write( "

\n" );
