To factor the quadratic expression \( x^2 + 2x - 8 \), we need to find two numbers that multiply to \(-8\) (the constant term) and add up to \(2\) (the coefficient of the \(x\) term).

The numbers that satisfy these conditions are \(4\) and \(-2\), since:

  • \(4 \times -2 = -8\)
  • \(4 + (-2) = 2\)

Using these numbers, we can factor the expression as follows:

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

Thus, the factored form of \( x^2 + 2x - 8 \) is:

\[ (x + 4)(x - 2) \]
