Final answer:

To use the quadratic formula on the function f(x) = x⁶ - 5x³ + x² - x - 6, rearrange the equation to get it in the form ax² + bx + c = 0. Substitute the values of a, b, and c into the quadratic formula, and solve for x. The solutions for the equation are x = 6 or x = -1.

Step-by-step explanation:

To use the quadratic formula on the function f(x) = x⁶ - 5x³ + x² - x - 6, we need to rearrange the equation to get it in the form ax² + bx + c = 0. So, we have:

x⁶ - 5x³ + x² - x - 6 = 0

Let a = 1, b = -5, and c = -6. Substitute these values into the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

=> x = (-(-5) ± √((-5)² - 4(1)(-6))) / (2(1))

=> x = (5 ± √(25 + 24)) / 2

=> x = (5 ± √49) / 2

=> x = (5 ± 7) / 2

Therefore, the solutions for the equation f(x) = x⁶ - 5x³ + x² - x - 6 are x = 6 or x = -1.
