To solve the quadratic equation x² - 2x - 8 = 0 using the quadratic formula, we can apply the formula:

$$x=\frac {-b\pm \sqrt {{b}^{2}-4ac}} {2a}$$

For the given equation, the coefficients are:
a = 1
b = -2
c = -8

Substituting these values into the quadratic formula:

$$x=\frac {-(-2)\pm \sqrt {{(-2)}^{2}-4(1)(-8)}} {...
