How do you use the rational roots theorem to find all possible zeros of # p(x)= 2x^5+7x^3+6x^2-15#?
Given this all what we need to do here is identify the factors of
so p⇒ ±1,±2 and q⇒±1,±2
and the ratio:
This are the potential roots, but remember they are not guaranteed... In this case you can try (x-1), use long division and see if you can divide without a remainder...
You were not asked to do that but you can divide
