x = - 3 or x = - 1

Solution steps

∣ x + 2 ∣ = 5 - 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 2 = - (5 - 4) or x + 2 = 5 - 4

x + 2 = - (5 - 4) or x + 2 = 5 - 4

x = - 3 or x = - 1

1 - \frac{1}{64}

\frac{27 π}{10} - 2 π

4 x^{2} + 25 x - 21 \leq 0

3 \cdot 2

x^{\frac{p}{q}}
