Simplify using the vertical method. (3k + 5)(2k² - 5k - 3)

Solution:

Given expression is (3k + 5)(2k² - 5k - 3)

Solving by the vertical method we have:

          2k² - 5k - 3
                  3k + 5
-------------------------
                 -9k - 15
             -15k² - 25k
      6k³ + 10k²
-----------------------------
      6k³ - 5k² - 34k - 15

Simplify using the vertical method. (3k + 5)(2k² - 5k - 3)

Summary:

Simplify using the vertical method. (3k + 5)(2k² - 5k - 3) we get 6k³ - 5k² -34k - 15
