|x-5|=4

∣ x - 5 ∣ = 4

x = 1 or x = 9

Solution steps

∣ x - 5 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x - 5 = - 4 or x - 5 = 4

x - 5 = - 4 or x - 5 = 4

x = 1 or x = 9

- 36 + x < 8 - 36 + x < 8

2 x^{2} + 34 x + 144 = 0

\frac{- 9}{2} x^{- \frac{11}{10}}

\frac{( c + 2 ) ( c - 1 )}{c + 2}

\frac{( x ^{2} + 1 )}{2} \geq 1
