factors of -26 : ?
ganeshie8 (ganeshie8):
factors of 13 : ?
OpenStudy (anonymous):
i got this ±1, ± 1/3, ±2, ±13, ±26
ganeshie8 (ganeshie8):
first have those two
ganeshie8 (ganeshie8):
factors of -26 : \(\pm 1, \pm 2, \pm 13, \pm26\)
factors of 13 : \(\pm 1, \pm 2, \pm 13\)

thats the only factors i can do?
ganeshie8 (ganeshie8):
one sec, i have them wrong.
ganeshie8 (ganeshie8):
factors of -26 : \(\pm 1, \pm 2, \pm 13, \pm26\)
factors of 13 : \(\pm 1 , \pm13\)
ganeshie8 (ganeshie8):
now we need to take p/q
ganeshie8 (ganeshie8):
p is from factors of -26
q is from factors of 13

1/2
ganeshie8 (ganeshie8):
p/q : \(\pm1, \pm 1/13, \pm2, \pm 2/13, \pm13, \pm26, \pm2\)
ganeshie8 (ganeshie8):
thats the list of potential rational zeroes
ganeshie8 (ganeshie8):
what we did is this : take each factor of -26, and divide it by
ganeshie8 (ganeshie8):
the each factor of 13
