Final answer:
The given expression is a quadratic equation of the form at² + bt + c = 0, where a = 4.90, b = 14.3, and c = -20.0. To find the solutions of the equation, we can use the quadratic formula.
Step-by-step explanation:
The given expression is a quadratic equation of the form at² + bt + c = 0, where the constants are a = 4.90, b = 14.3, and c = -20.0.
To find the solutions of the equation, we can use the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a.
Substituting the values into the formula, we can calculate the solutions.
