-2|x+8|+7=-21

- 2 ∣ x + 8 ∣ + 7 = - 21

x = - 22 or x = 6

Solution steps

- 2 ∣ x + 8 ∣ + 7 = - 21

Move

7

to the right side

- 2 ∣ x + 8 ∣ = - 28

Divide both sides by

- 2

∣ x + 8 ∣ = 14

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 8 = - 14 or x + 8 = 14

x + 8 = - 14 or x + 8 = 14

x = - 22 or x = 6

x^{2} - 11 x + 28 > 0

\frac{( d ^{2} y )}{d x ^{2}}

(- 36)^{\frac{1}{2}}

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

\frac{x ^{2} + 3 x + 2}{x + 1} \geq 0
