The polynomial negative 16 x squared plus 189 x plus 14 comma 414 represents the electricity generated​ (in gigawatts) by geothermal sources during 2002minus2007. The polynomial 822 x squared minus 79 x plus 10 comma 160 represents the electricity generated​ (in gigawatts) by wind power during 2002minus2007. In both​ polynomials, x represents the number of years after 2002. Find a polynomial for the total electricity generated by both geothermal and wind power during 2002minus2007.
