Let's analyze the phrase step by step:
1. "The product of 3 and a number squared": This can be expressed as \(3x^2\) where \(x\) is the number.
2. "minus the product of four and that same number": This can be expressed as \(-4x\).
3. "plus 5": This is simply \(+5\).
Now, we can combine these parts to form the complete expression:
\[
3x^2 - 4x + 5
\]
Thus, the expression that is equivalent to the given phrase is:
**C) 3x^2 - 4x + 5**.
