|x+2|=1

∣ x + 2 ∣ = 1

x = - 3 or x = - 1

Solution steps

∣ x + 2 ∣ = 1

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 2 = - 1 or x + 2 = 1

x + 2 = - 1 or x + 2 = 1

x = - 3 or x = - 1

100 = (160) x + \frac{1}{2} (- 9.81) x^{2}

x^{3} + x^{2} + x + 1

- \frac{3}{2} (\frac{1}{100}) + \frac{3}{2}
