|-x^2+4x-7|-x^2+4x-7=0

- x^{2} + 4 x - 7 - x^{2} + 4 x - 7 = 0

True for all x

Solution steps

- x^{2} + 4 x - 7 - x^{2} + 4 x - 7 = 0

Find positive and negative intervals

- \infty < x < \infty

Solve the inequality for each interval

True for all x

∣ x - 5 ∣ + ∣ x + 6 ∣ = ∣ 2 x + 1 ∣

x^{2} + 4 x - 5 = x^{2} - 1

∣ x - 3 ∣ + ∣ x - 2 ∣ = 1

x^{2} - 1 + 2 - x^{2} = 1

∣ x - 5 ∣ - ∣ 2 + x ∣ = 4
