Answer:

x =  - (2 \div  \sqrt{5}  ) \:  \: or \:  \: x =  -  \sqrt{5}

Step-by-step explanation:

 \sqrt{5}  {x}^{2}  + 5x + 2x + 2 \sqrt{5  }  \\   | =  \sqrt{5}x(x +  \sqrt{5} ) + 2(x +  \sqrt{5}  )  \\ = ( \sqrt{5} x + 2)(x +  \sqrt{5} )

So

( \sqrt{5} x + 2)(x +  \sqrt{5} ) = 0

So, Either

 \sqrt{5} x + 2 = 0 \:  \: or \: x +  \sqrt{5}  = 0

So,

x =  -(2 \div  \sqrt{5} ) \:  \: or \:  \: x =  -  \sqrt{5}
