Answer
2, -1
n = 2
n = -1
Step-by-step explanation
We need to factorize the given quadratic equation
5n² - 5n - 10 = 0
5n² - 10n + 5n - 10 = 0
5n (n - 2) + 5 (n - 2) = 0
(n - 2) (5n + 5) = 0
n - 2 = 0
OR
5n + 5 = 0
n - 2 = 0
n = 2
5n + 5 = 0
5n = -5
Divide both sides by 5
(5n/5) = (-5/5)
n = -1
Hope this Helps!!!
