Answer:

-3>_ x >_ -2

Step-by-step explanation:

x(x+5)>_  -6

Open the bracket

x² + 5x >_  -6

x² +5x + 6 >_  0

Solve quadratically using factorisation method

Factors of 6 that sum up to +5. ( 2 and 3)

x² + 2x + 3x + 6 >_  0

Factorise

x(x + 2) +3(x + 2) >_ 0

(x+2)(x+3) >_ 0

Therefore

x + 2 >_ 0    or  x +3 >_ 0

x>_ -2   or x >_ -3

-3>_ x >_ -2

I hope this was helpful, please mark as brainliest
