Complete the following:
(a) Determine the number of the real solutions of -x^2-4x+1=0
In , a = -1, b = -4, and c = 1.
The discriminant is .
If the discriminant is greater than zero, then there are two real solutions.
Answer: real solutions

(b) Use the quadratic formula to find the exact values of the real solutions, if they exist. Give the solution set.
The quadratic formula is .
The solution is
