x^{2} - 5 ∣ x ∣ - 4 = 0

x = \frac{- 5 - 41}{2} or x = \frac{5 + 41}{2}

Decimal Notation

x = - 5.70156 \dots, x = 5.70156 \dots

Solution steps

x^{2} - 5 ∣ x ∣ - 4 = 0

Find positive and negative intervals

x < 0, x \geq 0

Solve the inequality for each interval

x = \frac{- 5 - 41}{2} or x = \frac{5 + 41}{2}

∣ 1 - 4 m ∣ = 7

∣ x + 1 ∣ - 5 = 5

5 ∣ 2 x - 6 ∣ = 9

- 6 = - 7 ∣ m ∣

∣ 2 x - 1 ∣ = 4 + x
