1 answer

To find the quadratic equation that matches the given problem, let's break down the statement:

  1. "the product of negative six and a number squared" translates to: \(-6x^2\).
  2. "the product of five and the same number" translates to: \(5x\).
  3. The equation states that this sum is equal to thirty-one, so we set up the equation:

\(-6x^2 + 5x = 31\)

This matches the option:

−6x² + 5x = 31

So the correct response is:

−6x² + 5x = 31 (negative 6 x squared plus 5 x is equal to 31)
