Consider the equation:

4x^2 – 16x + 25 = 0

(a) Show how to compute the discriminant, b^2 – 4ac, and then state whether there is one real-number solution, two different real-number solutions, or two different imaginary-number solutions.

(b) Use the quadratic formula to find the exact solutions of the equation. Show work. Simplify the final results as much as possible.
