The fuel economy of car, measured in miles per gallon, is modeled by the function f(s) = -0.009s^2 + 0.699 + 12 where s represents the speed of the car, measured in miles per hour. What the fuel economy of the car when it travel at an average of 20 miles per hour

Find the zeros of each function. f(x) = x^2 + 5x - 6
