|10x+20|*|4x+8|=360

∣ 10 x + 20 ∣ \cdot ∣ 4 x + 8 ∣ = 360

x = - 5 or x = 1

Solution steps

∣ 10 x + 20 ∣ ∣ 4 x + 8 ∣ = 360

Find positive and negative intervals

x < - 2, x \geq - 2

Solve the inequality for each interval

x = - 5 or x = 1

x^{2} - 3 x ∣ + 2 ∣ = x^{2} - 2 x

x^{2} - 4 x + 3 = - x^{2} - 5 x + 4

∣ x + 2 ∣ + ∣ 2 x + 1 ∣ - 3 ∣ x - 1 ∣ = 6

∣ x + 4 ∣ - ∣ x ∣ = 4

x^{2} - 9 = ∣ 3 - 4 x ∣ + 9
