Helppppp!!! I don’t know what the answer is and I’m taking the test right now....

Darya [45]

Answer:

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>
