Use the x-intercept method to find all real solutions of the equation. x^3-9x^2+20x-12=0

For this case we have the following function:

x ^ 3-9x ^ 2 + 20x-12 = 0

Rewriting we have:

(x-6) * (x-2) * (x-1) = 0

Therefore, the solutions are given by:

Solution 1:

x-6 = 0

x = 6

Solution 2:

x-2 = 0

x = 2

Solution 3:

x-1 = 0

x = 1

Answer:

x = 6

x = 2

x = 1
