Answer: x² + 6x + 10
Step-by-step explanation:
The four can be factored by the set of real numbers, except the first one.
- x² + 3x - 4 can be factor as (x + 4)(x - 1)
- x² - 3x - 4 can be factor as (x - 4)(x + 1)
- x² + 3x - 4 can be factor as (x + 4)(x - 1)
And the first one, the number is 10, the factos of 10 is 1,2,5,10, none of the factors would apply the situation 6x.
