Darya [45]

Answer:

<h2>x =  - 4± \sqrt{2}</h2>

Step-by-step explanation:

Hint :

  • \frac{−b± \sqrt{{b}^{2} −4(ac} )}{2a}

Simplify :

{x}^{2} +8x+16=2

{x}^{2} +8x+16−2=0

{x}^{2} +8x+14=0

<h3>\frac{ - 8± \sqrt{ {8}^{2} - 4(1 \times 14) } }{2 \times 1}</h3><h3>x =  \frac{ - 8±2 \sqrt{2} }{2 \times 1}</h3><h3>x = \frac{- 8±2 \sqrt{2}}{2}</h3>

x =  - 4± \sqrt{2}

<h3>Hope it is helpful....</h3>
