(x-8)²= x²-16x+64
x²-16x+8=0
Therefore 56 must be added.
Good luck

Answer:
a. Negative discriminant: above
b. Positive discriminant: below
c. Discriminant is zero: on
Step-by-step explanation:
If the discriminant is negative, then there are no real zeros. We have an upward-facing parabola, then the vertex is located above the x-axis
If the discriminant is positive, then there are two different real zeros. We have an upward-facing parabola, then the vertex is located below the x-axis
If the discriminant is zero, then there is one zero. We have an upward-facing parabola, then the vertex is located on the x-axis
The fourth one or the second one on the bottom
Since there are two negative symbols your answer will be positive. Your answer is 57.5
