The equation for the midpoint of a line segment is

. Thus, the midpoint of this segment is

.
1/2 x^2 - x + 5 = 0
Multiply through by 2 to get:
x^2 - 2x + 10 = 0

; where a = 1, b = -2 and c = 10

Therefore, x = 1 + 3i or x = 1 - 3i
B) 16 + (5 + 2) - 1
I don’t know what C is
Answer:
1
Step-by-step explanation:
13 x 4 = 52
53 - 52 = 1
