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

(x−4)(x−8)=0

Answer 1

To factor the quadratic equation \( x^2 + 4x - 32 = 0 \), we need to find two numbers that multiply to \(-32\) (the constant term) and add to \(4\) (the coefficient of the middle term).

The two numbers that meet these criteria are \(8\) and \(-4\), since:

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

Therefore, the factored form of the equation is:

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

So the correct response is:

\((x+8)(x−4)=0\)
