A biologist studied the populations of black bear and brown bears over a 10-year period. The biologist modeled the populations, in thousands, with the following polynomials where x is time, in years.black bears: 2.3x2 – 5.6x + 2.3brown bears: 2.4x2 + 7.2x + 0.97What polynomial models the total number of brown and black bears?
