√(5+2√6) =√ (3+2+2√3√2) = √(√3+√2)^2 = √3+√2
in the same way
√(5-2√6) =√ (3+2-2√3√2) = √(√2-√3)^2 = √2-√3
√(5-2√6) - √(5+2√6)
= √2-√3-(√2 +√3)
= -2√3
√3+√(5-2√6) - √(5+2√6) = √3 - 2√3
= -√3
in the same way
√(5-2√6) =√ (3+2-2√3√2) = √(√2-√3)^2 = √2-√3
√(5-2√6) - √(5+2√6)
= √2-√3-(√2 +√3)
= -2√3
√3+√(5-2√6) - √(5+2√6) = √3 - 2√3
= -√3
