Explanation:
Setting
To solve quadratic equations, you need to set the equation equal to zero. By adding 12 to both sides, we get:
From here, we can factor the quadratic to
Using the Zero Product Property, we can solve the equation by setting each factor equal to zero and solving for x.
The two solutions are -3 and 1
