The quadratic equation x^2 + 4x-32=0 can be solved by factoring. Which of the following is the factored form?

1 answer

To factor the quadratic equation \( x^2 + 4x - 32 = 0 \), we are looking for 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 \(-4\), because:

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

Thus, we can factor the quadratic equation as follows:

\[ x^2 + 4x - 32 = (x + 8)(x - 4) \]

So, the factored form of the quadratic equation \( x^2 + 4x - 32 = 0 \) is:

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