Answer :

I see that you are solving a quadratic equation using the Quadratic Formula. In this case, the equation is 3x² - 4x = 10. Let's go through the steps to find the solutions: 1. Identify the coefficients in the equation: - In this case, the coefficients are: - a = 3 (coefficient of x²) - b = -4 (coefficient of x) - c = -10 (constant term) 2. Plug the coefficients into the Quadratic Formula: - The Quadratic Formula is x = (-b ± √(b² - 4ac)) / 2a 3. Substitute the values: - x = (4 ± √((-4)² - 4 * 3 * (-10))) / 2 * 3 - x = (4 ± √(16 + 120)) / 6 - x = (4 ± √136) / 6 4. Simplify the square root of 136: - √136 = √(4 * 34) = 2√34 5. Write down the solutions: - x = (4 ± 2√34) / 6 - x = (2 ± √34) / 3 Therefore, the solutions to the quadratic equation 3x² - 4x = 10 are: - x = (2 + √34) / 3 - x = (2 - √34) / 3 These are the correct solutions obtained by applying the Quadratic Formula to the given equation.
