Question Analysis
This question tests the student's ability to find the x-intercept of a quadratic function by factoring and applying the Zero Product Property. The quadratic function is given in standard form, and students need to recognize that it is a perfect square trinomial.

Key Concept Explanation
The x-intercepts of a quadratic function are the points where the graph intersects the x-axis, which are the solutions to the equation . By factoring the quadratic expression and setting each factor equal to zero, we can find these solutions. In this case, the quadratic is a perfect square trinomial.

Step-by-step Solution
1. Set the function equal to 0: .
2. Recognize that the quadratic is a perfect square trinomial:
