Problema Solution
The total imports of petroleum (in millions of barrels per day) in a given year is approximated by the polynomial 36x3-529x2+2089x+6054.Where x represents the number of years since 1975. The corresponding total of exports of petroleum is -x3+17x2+27x+187. Write the polynomial that represents how many more barrels per day were importes than exported in a given year. The polynomial is million barrels per day.
