\"4x%5E4-16x%5E2%2B15+=+%282x%5E2+-+5++%29%28+2x%5E2+-+3%29+=0\"
\n" ); document.write( "==> \"2x%5E2+-+5++=+0\" or \"2x%5E2+-+3+=+0\"
\n" ); document.write( "==> \"x%5E2+=+5%2F2\" or \"x%5E2++=+3%2F2\"
\n" ); document.write( "==> \"x+=+sqrt%285%29%2F2\", \"-sqrt%285%29%2F2\", \"sqrt%283%29%2F2\", and \"-sqrt%283%29%2F2\".
\n" ); document.write( "
