Answer 3

To solve the quadratic equation 3x² + kx - 9k + 1 = 0, you can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 3, b = k, and c = -9k + 1. Plug these values into the formula:

x = (-k ± √(k² - 4 * 3 * (-9k + 1))) / (2 * 3)

Now, simplify the equation:

x = (-k ± √(k² + 108k - 12)) / 6

Now, you have two possible solutions:

1. x₁ = (-k + √(k² + 108k - 12)) / 6
2. x₂ = (-k - √(k² + 108k - 12)) / 6

These are the solutions for the quadratic equation 3x² + kx - 9k + 1 = 0 in terms of k.
