sqrt%285%29%2A%287-sqrt%285%29%29%2B6%2Asqrt%285%29

sqrt%285%29%2A%287%29%2Bsqrt%285%29%2A%28-sqrt%285%29%29%2B6%2Asqrt%285%29

7%2Asqrt%285%29-5%2B6%2Asqrt%285%29

-5%2B13%2Asqrt%285%29

=======================================================

Therefore, sqrt%285%29%2A%287-sqrt%285%29%29%2B6%2Asqrt%285%29=-5%2B13%2Asqrt%285%29
