Explanation:

Step1: Factor the quadratic equation

Find two numbers that multiply to -12 and add to -4: -6 and 2.
$x^2 - 4x - 12 = (x - 6)(x + 2)$

Step2: Set factors to zero

$(x - 6)(x + 2) = 0$ implies $x - 6 = 0$ or $x + 2 = 0$

Step3: Solve for x

$x = 6$ or $x = -2$

Answer:

B. x = -2 or x = 6
