Hasil dari 2 akar 2 dikurang akar 6 dikali akar 2 ditambah akar 6

2√2 - √6 x √2 +√6 = 2√2 - √12 + √6
                             = 2√2 - √(2² x 3) + √(2x3)
                             = 2√2 - (2√2 .√3) + ( √2 .√3)
                             = 2√2 - √2√3
                             = (2 - √3)√2
