If that's
ferric oxide ==> iron + oxygen, then the first step is to changer the words to chemical formula.

Fe2O3 ==> Fe + O2

The next step is to balance the equation which you do by changing the coefficients. (You may change only the coefficients--you may NOT change the subscripts).
2Fe2O3 ==> 4Fe + 3O2
