GPT-5 mini · Answer

Use the quadratic formula x = [8.1 ± sqrt(8.1^2 − 4·1·10)]/2.

Compute the discriminant: 8.1^2 − 40 = 65.61 − 40 = 25.61, sqrt = 5.060632372...

Thus
x = (8.1 ± 5.060632372)/2,
giving x ≈ 6.580316186 and x ≈ 1.519683814.

Rounded to the nearest thousandth: x ≈ 6.580 and x ≈ 1.520.
