x^{2} - 1 = 169

x = - 170 or x = 170

Decimal Notation

x = - 13.03840 \dots, x = 13.03840 \dots

Solution steps

x^{2} - 1 = 169

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} - 1 = - 169 or x^{2} - 1 = 169

x^{2} - 1 = - 169 or x^{2} - 1 = 169

No Solution or (x = - 170 or x = 170)

x = - 170 or x = 170

∣ w - 39 ∣ = 3

x^{2} - 9 = - 3

∣ 16 - 3 x ∣ = - 4 x + 12

- 6 = - 8 ∣ - r - 9 ∣ - 6

13 ∣ - 2 x + 1 ∣ - 10 = 159
