Question

PLEASE HELP!!!! GIVING OUT MEDALS.
List the possible rational roots of P(x) given by the Rational Root Theorem.
P(x)= 3x^4-4x^3-x^2-7

anonymous · Answer

take all fractions where the numerator divides $7$ and the denominator divides $3$
don't forget the $\pm$

anonymous · Answer

sorry can you go a little more into depth?

anonymous · Answer

the divisors of $7$ are only $1$ and $7$
the divisors of $3$ are $1$ and $3$
$$\pm1,\pm 7,\pm\frac{1}{3},\pm\frac{7}{3}$$

anonymous · Answer

ohh okay. why do you choose 7 and 3?

anonymous · Answer

$7$ is the constant, the leading coefficient is $3$

anonymous · Answer

oh awesome thanks!

@satellite73 is there anyway you can look at this one for me too please? 
Find any rational roots of P(x).
P(x)=x^3+5x^2+x+5
