## puppy33 Group Title Use the Rational Zeros Theorem to write a list of all possible rational zeros of the function. f(x) = -2x^4 + 4x^3 + 3x^2 + 18 one year ago one year ago

1. malevolence19 Group Title

All the factors of 18. Namely, 1,2,3,6,9,18.

2. malevolence19 Group Title

+/- all those.

you need the positive and negative factors of the constant, 18 and call them p e.g. $\pm1, \pm2, \pm3, \pm 6, \pm9, \pm18$ and all the factors of the leading coefficient -2 and call them q. you can find them then the possible rational zeros are p/q
