x^{2} - 4 x - 4 = 8

x = - 2 or x = 2 or x = 6

Solution steps

x^{2} - 4 x - 4 = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} - 4 x - 4 = - 8 or x^{2} - 4 x - 4 = 8

x^{2} - 4 x - 4 = - 8 or x^{2} - 4 x - 4 = 8

x = 2 or (x = - 2 or x = 6)

x = - 2 or x = 2 or x = 6

3 x^{2} + 5 x - 2 = 0

- 10 x - 8 < x + 3

0 + \frac{π}{2}

3 y - 6 x + 4 x y - 2 y^{2}

2 x - \frac{1}{2} = \frac{7}{2}
