Cubic Roots E5D3Ef
1. **State the problem:** We are given the function $F(x) = x^3 - 12x^2 + 36x$ and we want to analyze or solve it.
2. **Formula and rules:** This is a cubic polynomial function. To find its roots, we set $F(x) = 0$ and solve for $x$.
3. **Set the equation:**
$$x^3 - 12x^2 + 36x = 0$$
4. **Factor the polynomial:**
First, factor out the greatest common factor $x$:
$$x(x^2 - 12x + 36) = 0$$
5. **Solve each factor:**
- From $x = 0$, one root is $x = 0$.
- For the quadratic $x^2 - 12x + 36 = 0$, use the quadratic formula or factorization.
6. **Factor the quadratic:**
$$x^2 - 12x + 36 = (x - 6)^2$$
7. **Solve the quadratic:**
$$(x - 6)^2 = 0 \\ x - 6 = 0 \\ x = 6$$
8. **Roots of the function:**
The roots are $x = 0$ and $x = 6$ (with multiplicity 2).
9. **Summary:**
The function $F(x) = x^3 - 12x^2 + 36x$ has roots at $x = 0$ and $x = 6$ (double root).
