1. **State the problem:** Factor the polynomial $4x^3 - 26x^2 + 30x$ completely.
2. **Identify the common factor:** Each term has a factor of $2x$, so factor it out first.
3. **Factor out the common factor:**
$$4x^3 - 26x^2 + 30x = 2x(\cancel{2}x^2 - \cancel{13}x + \cancel{15})$$
4. **Factor the quadratic inside the parentheses:** We want to factor $2x^2 - 13x + 15$.
5. **Find two numbers that multiply to $2 \times 15 = 30$ and add to $-13$:** These numbers are $-10$ and $-3$.
6. **Rewrite the middle term:**
$$2x^2 - 10x - 3x + 15$$
7. **Group terms and factor each group:**
$$= (2x^2 - 10x) + (-3x + 15)$$
$$= 2x(x - 5) - 3(x - 5)$$
8. **Factor out the common binomial:**
$$= (2x - 3)(x - 5)$$
9. **Write the complete factorization:**
$$4x^3 - 26x^2 + 30x = 2x(2x - 3)(x - 5)$$
**Final answer:** $2x(2x - 3)(x - 5)$
