use the rational root theorem to list all possible rational roots of the polynomial equation x^3-x^2-3=0 DONT FIND THE ACTUAL ROOTS

OpenStudy (anonymous):

Okay so first is what is a Rational Root Theorem? Do you know q and p? q is the leading coefficient and p is the last coefficient. Find the factors of each and divide each p with each q

OpenStudy (pagen13):

No..

OpenStudy (anonymous):

Follow the steps... x^3-x^2-3=0 1. Find the factors of p (3) - the last digit/coefficient 2. Find the factors of q (1) - the number in front of the first x 3. Divide each p factors with 1 factors (1/1 and 3/1) 4. Evaluate

OpenStudy (pagen13):

I am confused..

OpenStudy (anonymous):

Okay... Wanna go over step by step?

OpenStudy (anonymous):

Rational Root Theorem tells you that given a polynomial function with integer or whole number coefficients, a list of possible solutions can be found by listing the factors of the constant, or last term, over the factors of the coefficient of the leading term.

OpenStudy (anonymous):

Just remember that the last term, which in this case is -3 is P

OpenStudy (anonymous):

and the first term, which in this case is 1 because the first term is only x is Q

OpenStudy (pagen13):

Step by step?

OpenStudy (anonymous):

Sorry if I a taking time.. I am helping 10 people at once. x^3-x^2-3=0 3 is p 1 is q factors of 3: 1, 3 factors of 1: 1 (+-) 1/1 and 3/1 With these numbers, use the "Synthetic Division" to find which of these two is a possible rationale root of the polynomial.

What is synthetic division
