Simplify using the vertical method. (3k + 4)(3k² - 5k - 3)

Solution:

Given expression is (3k + 4)(3k² - 5k - 3)

Solving by the vertical method we have:

          3k² - 5k - 3
                  3k + 4
----------------------------
                 -9k - 12
       -15k² - 20k
9k³ + 12k²
----------------------------
9k³ - 3k² - 29k - 12

Simplify using the vertical method. (3k + 4)(3k² - 5k - 3)

Summary:

Simplify using the vertical method. (3k + 4)(3k² - 5k - 3) we get 9k³ - 3k² - 29k - 12
