Solution Steps

Step 1: Expand the Expression

First, we expand the given expression \(3x(x - 12x) + 3x^2 - 2(x - 2)^2\).

\[ 3x(x - 12x) = 3x(-11x) = -33x^2 \]

\[ -2(x - 2)^2 = -2(x^2 - 4x + 4) = -2x^2 + 8x - 8 \]

Step 2: Combine Like Terms

Next, we combine the like terms from the expanded expression:

\[ -33x^2 + 3x^2 - 2x^2 + 8x - 8 \]

Step 3: Simplify the Expression

Now, we simplify the expression by combining the coefficients of like terms:

\[ -33x^2 + 3x^2 - 2x^2 = -32x^2 \]

So, the simplified expression is:

\[ -32x^2 + 8x - 8 \]

Final Answer

\(\boxed{-32x^2 + 8x - 8}\)

Among the Core Values listed, Patient Centeredness stands out as particularly crucial in nursing in my opinion. Patient Centeredness ensures that care is tailored to the unique needs, preferences, and values of each patient. By prioritizing the patient's perspective, we as nurses can provide care that is more relevant and effective, leading to better health outcomes and increased patient satisfaction. Patient Centeredness also opens honest lines of communication between patients and healthcare providers. This helps in understanding the patient's concerns, preferences, and goals, which is essential for creating personalized care plans actively involved in their own health decisions. A patient-centered approach builds trust and trust is fundamental for effective care, as it encourages patients to share critical information and follow medical advice.
