|3x^2-300|=0

3 x^{2} - 300 = 0

x = - 10 or x = 10

Solution steps

3 x^{2} - 300 = 0

Apply absolute rule: If

∣ u ∣ = 0

then

u = 0

3 x^{2} - 300 = 0

3 x^{2} - 300 = 0 : x = 10, x = - 10

x = - 10 or x = 10

∣ 5 y - 15 ∣ = 10

5 ∣ 5 - 8 x ∣ = 30

- 2 ∣ 3 x - 9 ∣ + 1 = - 17

∣ 8 x + 5 ∣ + 5 = 2

1 - ∣ 3 x - 2 ∣ = 10
