A company distributes its product by train and truck. The cost of distributing by train can be modeled as -0.09x^2 + 34x - 100. and the cost of distributing by trucks can be modeled as -0.04x^2 + 22x - 175, where x is the number of tons of product distributed. write a polynomial that represents the difference between the cost of distributing by train and the cost of distributing by trucks
