Answer:

Option C

1.62 and -0.62

Step-by-step explanation:

v² - v - 1 = 0

From ax² + bx + c = 0

a = 1 b = -1 c = -1

Quadratic formula

x = -b +/- √b² - 4ac

--------------------------

2a

x = -(-1) +/- √-1² - 4 x 1 x -1

-----------------------------------

2(1)

x = 1 +/- √1 +4

-----------------

2

x = 1 +/- √5/2

x = 1 + √5/2 or x = 1 - √5/2

x = 1.618 or -0.618
