Use the zero product property to find the solutions to the equation (x + 2) (x + 3) = 12.
Quadratic equations are the equations that can have at most two roots. Their degree is equal to two. Let's solve a problem related to it.
Answer: The solutions to the equation (x + 2) (x + 3) = 12 are x = 1 and x = -6.
Let's understand the solution in detail.
Explanation:
We are given the equation (x + 2) (x + 3) = 12.
It can be rewritten as (x + 2) (x + 3) - 12 = 0.
Now, we expand the equation:
⇒ (x + 2) (x + 3) - 12 = 0
⇒ x2 + 5x + 6 - 12 = 0
⇒ x2 + 5x - 6 = 0
Now, we use splitting the middle term method to represent the above equation in product form:
⇒ x2 + 6x - x - 6 = 0
⇒ x(x + 6) - 1(x + 6) = 0
⇒ (x - 1) (x + 6) = 0
Now, we use the zero product property.
We can have two cases:
⇒ x - 1 = 0 or,
⇒ x + 6 = 0
Hence, we have two solutions: x = 1 and x = -6.
Hence, the solutions to the equation (x + 2) (x + 3) = 12 are x = 1 and x = -6.
