Thank you.

Is it 1 / (x² + x) + 1 / x² - x or (1 / x²) + x + 1 / x² - x?

And what do you want to do with it. Integrate? Differentiate? Put under a common denominator? Paint red?

The first one please, I would like to simplify it.

so you should try to put over a common denominator of x(x+1)(x-1):









.

You can check this by plugging in a value or two of x and seeing that you get the same answer for each expression.

Thanks so much for your help! I understand completely
