3|2x-1|=9

3 ∣ 2 x - 1 ∣ = 9

x = - 1 or x = 2

Solution steps

3 ∣ 2 x - 1 ∣ = 9

Divide both sides by

3

∣ 2 x - 1 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x - 1 = - 3 or 2 x - 1 = 3

2 x - 1 = - 3 or 2 x - 1 = 3

x = - 1 or x = 2

\frac{6 - 3 i}{- 2 + 5 i}

8 x^{2} + 2 = 5 x^{2}

u^{2} - 13 = - 36

- 4 x^{2} + 8 x + 44 = 16
