x^{2} - 4 ∣ x ∣ - 4 = 0

x = - 2 (1 + 2) or x = 2 (1 + 2)

Decimal Notation

x = - 4.82842 \dots, x = 4.82842 \dots

Solution steps

x^{2} - 4 ∣ x ∣ - 4 = 0

Find positive and negative intervals

x < 0, x \geq 0

Solve the inequality for each interval

x = - 2 (1 + 2) or x = 2 (1 + 2)

4 ∣ x + 11 ∣ = 44

9 - 3 ∣ x - 2 ∣ = 4

∣ b + 2 ∣ = 1

\frac{z}{4} + 5 = - 7

∣ x - 2 ∣ = 3 - x
