x^{2} - 30 x - 1 = 30

x = - 1 or x = 1 or x = 29 or x = 31

Solution steps

x^{2} - 30 x - 1 = 30

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} - 30 x - 1 = - 30 or x^{2} - 30 x - 1 = 30

x^{2} - 30 x - 1 = - 30 or x^{2} - 30 x - 1 = 30

(x = 1 or x = 29) or (x = - 1 or x = 31)

x = - 1 or x = 1 or x = 29 or x = 31

∣ 2 x - 1 ∣ + ∣ x ∣ = 7

∣ m + 6 ∣ + 1 = 2

x, ∣ 15 - 9 x ∣ = 48

∣ x - 5 ∣ = - 7

∣ x ∣ - ∣ y ∣ = 5
