**Solution:**

Given expression is (3k + 4)(3k^{2} - 5k - 3)

Solving by the vertical method we have:

3k^{2} - 5k - 3

3k + 4

----------------------------

-9k - 12

-15k^{2} - 20k

9k^{3} + 12k^{2}

----------------------------

9k^{3} - 3k^{2} - 29k - 12

## Simplify using the vertical method. (3k + 4)(3k^{2} - 5k - 3)

**Summary:**

Simplify using the vertical method. (3k + 4)(3k^{2} - 5k - 3) we get 9k^{3} - 3k^{2} - 29k - 12
