x^2+4x-10>0

Solution

x^{2} + 4 x - 10 > 0

Solution

x < - 14 - 2 or x > 14 - 2

+2

Solution steps

x^{2} + 4 x - 10 > 0

Complete the square

x^{2} + 4 x - 10 : (x + 2)^{2} - 14

(x + 2)^{2} - 14 > 0

Move

14

to the right side

(x + 2)^{2} > 14

For

u^{n} > a

, if

n

is even then

x + 2 < - 14 or x + 2 > 14

x + 2 < - 14 : x < - 14 - 2

x + 2 > 14 : x > 14 - 2

Combine the intervals

x < - 14 - 2 or x > 14 - 2
