Answer:x = ±√(-108)
Explanation:
To solve the equation 3x^2 + 8 = -316 using the square root method, first, we isolate the x^2 term by subtracting 8 from both sides:
3x^2 = -324
Next, divide both sides by 3 to isolate the x^2 term:
x^2 = -324/3
x^2 = -108
Taking the square root of both sides, we have:
x = ±√(-108)
