what are the factors of x^2 - 8x - 48

1 answer

To factor the quadratic expression \( x^2 - 8x - 48 \), we need to find two numbers that multiply to the constant term (-48) and add up to the linear coefficient (-8).

  1. The numbers that satisfy these conditions are -12 and 4, since:

    • \( -12 \times 4 = -48 \)
    • \( -12 + 4 = -8 \)
  2. Now, we can rewrite the quadratic expression using these two numbers: \[ x^2 - 8x - 48 = (x - 12)(x + 4) \]

Thus, the factored form of \( x^2 - 8x - 48 \) is \((x - 12)(x + 4)\).
