Equity Valuation

I really need your help ,is it possible to get -ve FCFF AND +ve FCFE

Can you refer to a particular LOS? I can get the formula for FCFF and FCFE , and they have differnet variables: FCFE = Net Income - Net Capital Expenditure - Change in Net Working Capital + New Debt - Debt Repayment FCFF= operating cash Flow- Expenses-Changes in Net Working Capital-Changes in Investments As per me, since, FCFF can be -ve with +ve FCFE, for example when the firm has _ve Net capital exp. ( i.e firm sold more fixed assets than it bought in the year). It would be helpful if you can elaborate
