To translate the phrase "The product of 3 and a number squared, minus the product of four and that same number, plus 5" into an algebraic expression, we can define the number as \( x \).
- "The product of 3 and a number squared" translates to \( 3x^2 \).
- "Minus the product of four and that same number" translates to \( -4x \).
- "Plus 5" is simply \( +5 \).
Putting it all together, the expression becomes:
\[ 3x^2 - 4x + 5 \]
Thus, the equivalent expression is:
3x² - 4x + 5.
