I was wondering if I can ask one more question.
I am working trying to rationalizing the denominator and having trouble understanding the last part of the solution.
The textbook says
1-sq rt of 2 / -1
the answer is sq root of 2 - 1
I get of 1/-1 = -1 but I do not understand how the - in front of the sq rt of 2 is removed?
woukd you mind helping?
