Which statements are true about the polynomial function? f(x)=x^4+5x^3−x^2−5x select each correct answer. f(5)=0 f(x)=0 when x=−5 . f(x) divided by (x+5) has a remainder of 0. (x−5) is a factor of f(x) .

ANSWER

The second and third options are correct

EXPLANATION

We were given,

So we find by plugging in .

Hence

The first option is out.

Now we find by plugging in .

Hence when  . This is one of the correct options.

Since ,  , is a solution, this means that

is a factor of the polynomial by the factor theorem

Sice ,    is not a solution, this means that

is a not  factor of the polynomial by the factor theorem

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
