What is the difference between x⁻² and -x?

Question

I have no clue!!

Answer 1

As an explanation of notation:

    x^-2  is a way of writing  1/x²    [negative exponents mean positive exponents in the denominator]

 

    -x    means the opposite (negative) of x

 

Now, if you mean "difference" as in subtraction:

     x^-2 - (-x)   is how to write the difference

 

   so,   1/x² - (-x)

          1/x² + x             [distribute the implied (-1)]
