Final answer:
The question seems to be related to simplifying an expression using the quadratic formula. Since the full equation or specific context isn't provided, we cannot give a definitive answer but using a general substitution example for a, b, and c shows how the quadratic formula is used to find x.
Step-by-step explanation:
To simplify the expression given, which seems to be related to the quadratic formula, we need to substitute the given values into the quadratic formula. The quadratic formula is x = (-b ± √(b² - 4ac)) / (2a). Based on the provided snippets of solutions, various values for variables a, b, c have been shared, which are plugged into this formula to find x. However, without a clearer context or the original equation, we cannot determine which set of values corresponds to the equation you're attempting to simplify.
Nonetheless, if we take a typical example where a = 1, b = 0.0211, and c = -0.0211, plugging in these values yields:
x = -0.0211 ± √((0.0211)² - 4 × 1 × (-0.0211)) / (2 × 1)
After performing the operations under the square root and finishing the computation, we arrive at two possible solutions for x, one by adding and the other by subtracting the square root term from -0.0211.
To check the answer and ascertain if it's reasonable, compare it to the nature of the given problem and ensure that the computations and logical processes were followed accurately.
