x^{3} - 3 x - 2 = 0.2

x = - 1.24814 \dots or x = - 0.72929 \dots or x = 1.97743 \dots or x = 2.02190 \dots

Solution steps

x^{3} - 3 x - 2 = 0.2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{3} - 3 x - 2 = - 0.2 or x^{3} - 3 x - 2 = 0.2

x^{3} - 3 x - 2 = - 0.2 or x^{3} - 3 x - 2 = 0.2

(x = - 1.24814 \dots or x = - 0.72929 \dots or x = 1.97743 \dots) or x = 2.02190 \dots

x = - 1.24814 \dots or x = - 0.72929 \dots or x = 1.97743 \dots or x = 2.02190 \dots

2 ∣ 3 x - 6 ∣ = 18

∣ t + 9 ∣ = 1

2 - 2 ∣ 5 x - 2 ∣ = - 18 - 18

- 10 = ∣ 5 r ∣

∣ x - 3 ∣ = 4 x + 9
