|2x-5|=11

∣ 2 x - 5 ∣ = 11

x = - 3 or x = 8

Solution steps

∣ 2 x - 5 ∣ = 11

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x - 5 = - 11 or 2 x - 5 = 11

2 x - 5 = - 11 or 2 x - 5 = 11

x = - 3 or x = 8

x^{5} - 50 x^{3}

2 (x - 8)^{2} + 40 = 16

\frac{5}{4} + \frac{1}{2}

3 x^{2} + 12 x - 6 = 0

x^{5} + 6 x^{4} y + 9 x^{3} y^{2} + x^{2} y^{3} + 6 x y^{4} + 9 y^{5}
