Answer: 
Step-by-step explanation:
Given the quadratic equation
, you need to factor it.
In order to find the form asked of the given equation, you need to factor out the common factor of the terms.
You can observe that the common factor of the terms of the equation is: 
Now, knowing this, you must factor out
. Then you get the following form:

Therefore, the factored fom of the equation
is:
