x^{2} - 10 x + 20 = 4

x = 2 or x = 4 or x = 6 or x = 8

Solution steps

x^{2} - 10 x + 20 = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} - 10 x + 20 = - 4 or x^{2} - 10 x + 20 = 4

x^{2} - 10 x + 20 = - 4 or x^{2} - 10 x + 20 = 4

(x = 4 or x = 6) or (x = 2 or x = 8)

x = 2 or x = 4 or x = 6 or x = 8

3 ∣ m ∣ = 15

x - ∣ 2 x - 3 (x - 4) ∣ = 5

5 \frac{x - 4}{3} = 40

∣ x + 5 ∣ = 2 x + 3

∣ 4 x + 2 ∣ = - 18
