AnswerFor problems like these, the most important thing to remember is that when moving a power from the denominator to the numerator, we reverse the sign of the power
In this case, the power of the denominator is 6. Moving it to the numerator, it becomes -6.

Adding the 2 powers, we get
x
½ - x
6Converting 6 to a fraction by multiplying top and bottom by 2, we get
x
½ - x

We have our answer: x
