Identify the components in the expression \( H(x) + C N(x) - H C(x) \). Here, \( H(x) \), \( C N(x) \), and \( H C(x) \) are terms that need to be evaluated or simplified.
Step 2: Analyze the Given Information
The expression includes a statement \(\hat{1} = 820\). Determine if this information is relevant to the expression or if it provides any specific values for the terms in the expression.
Step 3: Simplify the Expression
Attempt to simplify the expression \( H(x) + C N(x) - H C(x) \) by combining like terms or factoring, if possible. Consider any potential relationships or identities that might apply to the terms \( H(x) \), \( C N(x) \), and \( H C(x) \).
