(x-2)^2>(x+2)-(x-2)+8

(x - 2)^{2} > (x + 2) - (x - 2) + 8

x < - 23 + 2 or x > 23 + 2

Solution steps

(x - 2)^{2} > x + 2 - (x - 2) + 8

Rewrite in standard form

x^{2} - 4 x - 8 > 0

Complete the square

x^{2} - 4 x - 8 : (x - 2)^{2} - 12

(x - 2)^{2} - 12 > 0

Move

12

to the right side

(x - 2)^{2} > 12

For

u^{n} > a

, if

n

is even then

x - 2 < - 12 or x - 2 > 12

x - 2 < - 12 : x < - 23 + 2

x - 2 > 12 : x > 23 + 2

Combine the intervals

x < - 23 + 2 or x > 23 + 2

2 y - 7 \geq - 14

6 4^{\frac{1}{3}}

- 21 - 6 k \leq - 4 (2 k + 6) + 2 k
