The final value for the coefficient is 5 or -5 and is located in the numerator or denominator.

The final value for the exponent for variable x is 4, -4, 5, or -5 and is located in the numerator or denominator.

If there is no value to place in the numerator or denominator, a 1, 0, or x is inserted to hold the place value. ​
