Answer:
k = 0 and k = -1
Step-by-step explanation:
To solve this, first distribute the terms inside the parenthesis. This should give you: k^2 + k - 3k^2 - 3k
Then, combine like terms to get: -2k^2 - 2k = 0
In this, you can factor out a -2k, giving you the new equation: -2k (k + 1) = 0
Set -2k equal to 0 and k + 1 equal to 0.
-2k = 0
Divide -2 onto both sides, leaving you with k = 0
k + 1 = 0
Subtract 1 from both sides, leaving you with k = -1
