<h2>Explanation:</h2>
In this exercise, we have the following equation:

We can write this Quadratic Equation in Standard Form as follows:

So this is a Non-perfect Square Trinomial. To factor out this, let's choose two numbers such that:
- The sum is -14
- The product is 24
Those numbers are:
- -12 and -2
- SUM: -12-2 = -14
- PRODUCT: (-12)(-2)=24
So we can write this as:
