Rationalize 2 divided by 1 minus the square root of 2.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

2%2F%281-sqrt%282%29%29 = %282%2F%281-sqrt%282%29%29%29%2A%28%281%2Bsqrt%282%29%29%2F%281%2Bsqrt%282%29%29%29.



In the numerator, you have  2%2A%281%2Bsqrt%282%29%29 = 2%2B2%2Asqrt%282%29.


In the denominator, you have  %281-sqrt%282%29%29%2A%281%2Bsqrt%282%29%29 = 1 - 2 = -1.


Therefore, the original fraction  2%2F%281-sqrt%282%29%29  is   -2-2sqrt%282%29.   ANSWER
