(x−4)(x−8)=0

Answer 1

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

The numbers \(8\) and \(-4\) meet these criteria because:

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

Thus, we can factor the quadratic as follows:

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

Therefore, the correct factored form is:

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