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 expression, we can break it down step by step.
- "The product of 3 and a number squared" can be written as \( 3x^2 \) (where \( x \) is the number).
- "minus the product of four and that same number" translates to \( -4x \).
- "plus 5" simply adds 5.
Combining these parts, the expression becomes: \[ 3x^2 - 4x + 5 \]
Thus, the equivalent expression is: 3x² - 4x + 5.
