First, isolate $x^2$ by subtracting 2 from both sides, resulting in $x^2 = 169$. Taking the square root of both sides gives $x = \pm \sqrt{169}$, which simplifies to $x = \pm 13$.

Use the Square Root Method to - x2+2=171x ^ { 2 } + 2 = 171x2+2=171

Use the Square Root Method to
- $x ^ { 2 } + 2 = 171$
