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 should test the remaining 4 roots.
3. He can stop testing because he has found all the roots.
4. He needs to pick one of the roots and use the quadratic formula to test it.

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
