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.

What is your question. The problem is rather self-explanatory.
