Question

Choose one of the factors of x6 + 1000

x2

x2 – 10

x4 – 10x2 + 100

x4 + 10x2 + 100

Answer 1

There are lot of possible factors. One possible factor that is in choices is x2. This is done using elimination process of choices because there are a lot of factors, x2 - 10 is not possible because x^6 is only 1. Then the other 2 is impossible since they still uses 10x2
