Question 15 • Applications and Modeling
First write the quadratic in standard form, ax² + bx + c = 0, and identify the values of a, b, and c. Then substitute those values into the Quadratic Formula, x = (−b ± √(b² − 4ac))/(2a), and simplify to find the solutions. This matches “find values for a, b, c, substitute into the formula, simplify.”
