Answer:
5/2
this is the answer to your question
8x² - 2x - 1 = 0
8x² - 4x + 2x - 1 = 0
4x (2x - 1) + 1 (2x - 1) = 0
(4x + 1)(2x - 1) = 0
4x + 1 = 0 or 2x - 1 = 0
x = -1/4 0r x = 1/2

Answer: um, you mean 10 + 122=132, the second one is n>4 if you want step by step look below:
Let's solve your inequality step-by-step.
3n>12
Step 1: Divide both sides by 3.
3n/3 > 12/3
n>4
