Answer:

Below.

Step-by-step explanation:

a. Φ^2 − Φ − 1 = 0

Φ2 − Φ = 1

(Φ - 0.5)^2 - 0.25 = 1

(Φ - 0.5)^2 = 1.25

Φ - 0.5 = √(1.25) (We only take the positive root).

Φ = 0.5 + √(1.25)

b. I used Completing the square.

c. Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.

Proportions and stuff.

$\frac{204}{4}$ = $\frac{918}{x}$

Cross multiply,

204x = 918 * 4

204x = 3672
/204 /204
x = 18
