Show all work to factor x^4 − 5x^2 + 4 completely. (With the Steps)
Question 2: Show all work to solve 3x^2 − 5x − 2 = 0. (With the Steps)
Question 4: The functions f(x) = (x + 1)^2 − 2 and g(x) = −(x − 2)^2 + 1 have been rewritten using the completing-the-square method. Apply your knowledge of functions in vertex form to determine if the vertex for each function is a minimum or a maximum and explain your reasoning.
