The quadratic equation x^2 + 0.0211x - 0.0211 = 0 can be solved using the quadratic formula to find the values of x.
The correct answer to the given question is option A).
The given equation is quadratic in form. To solve for x, we can rearrange the equation to get x^2 + 0.0211x - 0.0211 = 0.
To solve this quadratic equation, we can use the quadratic formula. The quadratic formula is x = (-b ± sqrt(b^2 - 4ac)) / (2a), where a = 1, b = 0.0211, and c = -0.0211.
Substituting the values into the quadratic formula, we get x ≈ 409 or x ≈ -0.0211.
