6 and - 4

Step-by-step explanation:

$x^2 - 2x - 24 = 0 \\\ \Delta = (- 2)^2 - 4.1.(- 24) \\\ \Delta = 4 + 96 \\\ \Delta = 100 \\\ x' = \frac{- (- 2) + \sqrt{100}}{2.1} \\\\ x' = \frac{2 + 10}{2} \\\\ x' = 6 \\\ x" = \frac{- (- 2) - \sqrt{100}}{2.1} \\\\ x" = \frac{2 - 10}{2} \\\\ x" = - 4$

I hope I helped you.
