To find which equations have the solution set of {12, -3}, we can use the fact that if a polynomial equation has a certain set of roots, it can be factored accordingly. The roots can be expressed in the form of factors:

If the roots are \( x = 12 \) and \( x = -3 \), then the corresponding factors will be \( (x - 12) \) and \( (x + 3) \).

Thus, the polynomial can be represented as:

\[ (x - 12)(x + 3) = 0 \]

Let's analyze the given options:

  1. (4x - 2)(x + 3) = 0:

    • This does not yield a root of 12 or -3.
  2. (x - 12)(x + 3) = 0:

    • This matches perfectly with our expected factors, yielding the roots 12 and -3.
  3. (3x - 6)(3x - 6) = 0:

    • This simplifies to \( (3(x - 2))^2 = 0 \), giving x = 2 as the only solution.
  4. (6x - 3)(4x + 12) = 0:

    • Simplifying gives roots for \( x = \frac{1}{2} \) and \( x = -3 \), but not 12.
  5. (x - 12)(x + 3) = 0 (same as before):

    • This also matches perfectly, yielding the roots 12 and -3.
  6. (x - 12)(x - 3) = 0:

    • This gives the roots 12 and 3, not -3.
  7. (4x + 2)(x + 3) = 0:

    • This gives no roots of 12 and -3.

Based on the analysis:

The equations that have the solution set of {12, -3} are:

  • (x - 12)(x + 3) = 0
  • (x - 12)(x + 3) = 0 (duplicate; counted only once)

The selected equations are:

  • (x - 12)(x + 3) = 0 (from both occurrences).

So the final answer is:

  1. \( (x - 12)(x + 3) = 0 \) (first occurrence)
  2. \( (x - 12)(x + 3) = 0 \) (second occurrence)
