Four different methods of solving a quadratic equation have been discussed: factoring, the square root property, completing the square, and the quadratic formula. Explain under what circumstances each method would be preferred over any of the other methods. Give an example for each circumstance.
What is the square root property and what is it used for? In what form should an equation be, in order to use the square root property? When should the square root property be used instead of factoring?

A boat is cruising at a constant speed of 20 ft/sec along a course that is parallel to a straight shoreline and 100 ft from it. A spectator standing on the shore begins to videotape the boat as soon as it passes him. (See the attached diagram.) Find the rate at which the spectator must rotate his camera in order to keep the boat
The following table represents weekly sales of a product (in $1,000s). Week Sales 1 14 2 13 3 17 4 14 Forecast sales for week 5 using exponential smoothing with a smoothing constant of 0.4 . Assume the forecast for week 1 is perfect.
In an exponential smoothing model, if the smoothing constant (alpha) were equal to 0, then a. the forecast would never change. b. the forecast would be the same as the forecast for the naive model. c. the MAD would always equal 0. d. the forecast would be impossible to calculate.
In your own words, explain the process of factoring a trinomial with a leading coefficient that is not equal to one. Why is this process more difficult than when the leading coefficient is equal to one? Give an example.
