Answer:
If you're just trying to simplify it, the answer is:
x² - 1
If you're trying to factor that answer, the answer is:
(x-1)(x+1)
Step-by-step explanation:
Firstly, you need to combine like terms:
6x² - 4x² - x² = x²
2 - 1 = 1
x² + 1
Then, if you're looking to factor, x² - 1 is simply (x-1)(x+1).
