Question

simplify (underroot5-2/underroot5+2)-(underroot5+2/underroot 5-2)

Answer 1

Answer:

$( \sqrt{5} - 2 \sqrt{5} + 2 ) - ( \sqrt{5} + 2 \sqrt{5} - 2) \\ \\ \sqrt{5} - 2 \sqrt{5} + 2 - \sqrt{5} - 2 \sqrt{5} + 2 \\ \\ 4 - 4 \sqrt{5} \\ \\ 4(1 - \sqrt{5} )$

Answer 2

Answer: 0 is the correct answer
