Solution steps

∣ 2 x ∣ = 2 x^{2} + x - 4

Find positive and negative intervals

x < 0, x \geq 0

Solve the inequality for each interval

x = \frac{- 3 - 41}{4} or x = \frac{1 + 33}{4}

\frac{15}{20}

2 k + 1 \geq 7

(x^{2})^{\frac{3}{4}} \cdot x^{\frac{1}{2}}

3 x^{2} + 16 x - 12

2 x^{2} + x - 168 = \frac{3}{4} x^{2} + 2 x
