Question 413114: 1) Explain how you might go about constructing a quadratic equation whose solutions are -5 and 7.
2) The connection between the graph and the equation is an important and helpful one! Briefly discuss the effect of the sign of the coefficient a on the graph of y = ax2 + bx + c. Please include two examples of graphs to support your thoughts, one where a < 0 and one where a > 0. (It is encouraged but not required to include the graphs of your examples in your post. If you do not include the actual graphs, please describe your examples in detail with words.)
