Answer:
B
Step-by-step explanation:
There are 4 pairs, so any answer with less or more is wrong.
The first pair is (1,3), i.e., you always write (x,y) with x first, y second, and so on.
That leaves answer B.
Hope this helps explain what was needed to be solved! :)
Answer:
There are no positive roots
Step-by-step explanation:
The Descartes' rule posits that, given a polynomial with real coefficients ordered, the number of positive roots is equal to the amount of sign-changes OR to such amount minus a number multiple of 2. In you polynomial P(x)=x^3+6x^2+9x+5 you have NO sign-changes, as every coefficient is positive. So, we can confirm that, if the polynomial has real roots, none of these are positive. As 0 can'y be a root of P(x) (replace x=0 and confirm), if there is some root, it will be a negative root. However, the rule can't confirm that there are roots.
