by using the the rational root test ?!
OpenStudy (anonymous):
still there? @cassie4math
OpenStudy (anonymous):
yah! i think what ever gets to the answer idk how to do this problem
OpenStudy (anonymous):
you know what does "the the rational root test" refer to ? :)

oh ! kk I'll explain it to you !
OpenStudy (anonymous):
k ;)

The rational root theorem :
is a theorem that can help us to find rational root of a polynomial functions !
rational root must be in this form \[x= \pm \frac{p}{q}\]
so this theorem tell us that p is a divisor of 14 and q is a divisor of 2
OpenStudy (anonymous):
why 14 and 2 ?!
OpenStudy (anonymous):
so 14 is the constant term ! (the last one)
and 2is the leading coefficient [the coefficient of "the biggest degree")
