(|x^2|)/4 =1

\frac{x ^{2}}{4} = 1

x = - 2 or x = 2

Solution steps

\frac{x ^{2}}{4} = 1

Multiply both sides by

4

x^{2} = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} = - 4 or x^{2} = 4

x^{2} = - 4 or x^{2} = 4

No Solution or (x = - 2 or x = 2)

x = - 2 or x = 2

∣ x + 9 ∣ + ∣ x - 3 ∣ + ∣ x + 7 ∣ + ∣ x - 4 ∣ = 8

∣ b ∣ = - 2

∣ x - 4 ∣ + 5 = 10

7 ∣ 2 - 2 n ∣ + 10 \leq = - 18

∣ 10 x - 19 ∣ = ∣ 12 x - 25 ∣
