Question

Which statements are true about the polynomial function?

Answer 1

Answers:

First statements: True

`(-5)^4+5(-5)^3+(-5)^2-5(-5)=0`

Second statement: False

`(x^4+5x^3+-x^2-5x)/(x+5) = x (x - 1) (x + 1)`

Third statement: False

5 is not a root of this polynomial, therefore (x-5) is not one of its factors/

Fourth statement: False

5 is not a root of this polynomial, therefore f(5) does not equal 0.
