Final answer:
The question lacks the actual quadratic equation to solve, making it impossible to determine which set of values is in simplest form. The provided equations and constants are not sufficient without the specific quadratic equation they are meant to solve.
Step-by-step explanation:
The student's question seems to be related to finding the solution to a quadratic equation in the form at² + bt + c = 0. The values mentioned for a, b, and c do not appear to match with the provided equations and corresponding constants. However, if we look at the provided solutions and the form of the quadratic equation, we can focus on the use of the quadratic formula to find the roots of the equation, which is -b ± √(b² - 4ac) / 2a. A correct set of values for a, b, and c would be needed to use the quadratic formula properly, and the question must provide the quadratic equation they are attempting to solve to determine the values that represent the answer in its simplest form.
Without a specific equation, we cannot determine the simplicity or correctness of the given values of a, b, and c. Therefore, we would need the actual quadratic equation to proceed with the solution and to verify which of the provided options represent the answer in simplest form.
