x^{2} + 3 x - 20 = 20

x = - 8 or x = - 3 or x = 0 or x = 5

Solution steps

x^{2} + 3 x - 20 = 20

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} + 3 x - 20 = - 20 or x^{2} + 3 x - 20 = 20

x^{2} + 3 x - 20 = - 20 or x^{2} + 3 x - 20 = 20

(x = - 3 or x = 0) or (x = - 8 or x = 5)

x = - 8 or x = - 3 or x = 0 or x = 5

x^{2} - 5 = 5 x + 9

6 ∣ - 4 a - 10 ∣ = 84

9 ∣ t ∣ = 0

4 ∣ 2 x ∣ - 8 = 16

4 ∣ m - 4 ∣ = 14
