%283-sqrt%2814%29%29%5E2
%283-sqrt%2814%29%29%2A%283-sqrt%2814%29%29 This is FOIL problem.

9+-+3sqrt%2814%29+-+3sqrt%2814%29+%2B+sqrt%2814%29%2Asqrt%2814%29

Remember that the middle terms combine together, and also that sqrt%2814%29%2Asqrt%2814%29+=+14
So, 9+-6sqrt%2814%29+%2B+14

Combine 9 + 14 = 23
23+-+6sqrt%2814%29

P.S. Warning: Do NOT combine the 23 - 6 !!
