Answer:

x =  ± \sqrt{18}  - 4

Step-by-step explanation:

 {x}^{2}  + 8x - 2 = 0

 {x}^{2}  + 8x = 2

Multiply 8x by 2/2.

  {x}^{2}  + 8x \times  \frac{2}{2}  = 2

 {x}^{2}  + 2(x)(4) = 2

Add 4 ^2 on both sides

 {x}^{2}  + 2(x)(4) +  {4}^{2}  = 2 +  {4}^{2}

 {(x + 4)}^{2}  = 18

x  + 4 =  \sqrt{18}

x =  +  \sqrt{18}  - 4

x =   - \sqrt{18}   - 4
