Given x = √2-1
So, x-1÷x will be √2-1 -1÷√2-1 = √2-2÷√2-1
√2-2 / √2-1 = √2(1-√2) / √2-1
taking (-) as common on numerator (1-√2) will become -(√2-1)
= - √2(√2-1) / √2-1
= -√2
Therefore x-1÷x value (when x = (√2-1)) is -√2
So, x-1÷x will be √2-1 -1÷√2-1 = √2-2÷√2-1
√2-2 / √2-1 = √2(1-√2) / √2-1
taking (-) as common on numerator (1-√2) will become -(√2-1)
= - √2(√2-1) / √2-1
= -√2
Therefore x-1÷x value (when x = (√2-1)) is -√2
