Let's first translate the given statement into a mathematical equation.
The statement is: "the product of negative six and a number squared, plus the product of five and the same number is thirty-one."
This can be broken down as follows:
- "the product of negative six and a number squared" translates to \(-6x^2\).
- "the product of five and the same number" translates to \(5x\).
- "is thirty-one" translates to \(= 31\).
Putting it all together, we get the equation:
\[ -6x^2 + 5x = 31 \]
Thus, the correct answer is:
-6x^2 + 5x = 31
