x^{2} + x - 28 = 28

x = - 8 or x = - 1 or x = 0 or x = 7

Solution steps

x^{2} + x - 28 = 28

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} + x - 28 = - 28 or x^{2} + x - 28 = 28

x^{2} + x - 28 = - 28 or x^{2} + x - 28 = 28

(x = - 1 or x = 0) or (x = - 8 or x = 7)

x = - 8 or x = - 1 or x = 0 or x = 7

∣ x + 5 ∣ = - 9

∣ x + 5 ∣ = - 4

∣ x + 5 ∣ = - 6

∣ x + 5 ∣ = 11

3 ∣ 2 x - 5 ∣ + 4 = 9 x + 16
