To solve the quadratic equation \( x^2 + 4x - 32 = 0 \) by factoring, we want to find two numbers that multiply to \(-32\) (the constant term) and add to \(4\) (the coefficient of the linear term).

The numbers that satisfy these conditions are \(8\) and \(-4\), since:

  • \(8 \times (-4) = -32\)
  • \(8 + (-4) = 4\)

Thus, we can factor the quadratic equation as:

\[ (x + 8)(x - 4) = 0 \]

So, the correct factored form is:

\[ (x + 8)(x - 4) = 0 \]

This corresponds to the response:

(x + 8)(x - 4) = 0.
