What are the solutions of x2 - 2x +17 = 0 ?

a. x = 2i or x = -2i
b. x = 1+ 4i or x = 1 -4i
c. x= 4i or x = -4i
d. x = 1+2i or x = 1 - 2i

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
