Zidan is using the Rational Root Theorem to help find the roots of a 5th degree polynomial. He has discovered five roots and still has 4 to test. What is his next best step? 1 He should use the Factor Theorem to find the remaining polynomial roots.

2 He needs to pick one of the roots and use the quadratic formula to test it.

3 He should test the remaining 4 roots.

4 He can stop testing because he has found all the roots.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

the answer is a i belaeve atleast thats what my calculator just gfave me
