Last help questions for the day! I honestly appreciate all that you all have done for me so far it has been a great help and I hope to return the favor soon For f(x) = 2x⁴ + 5x³ -6x² -x +8
1. List all possible rational zeros of f(x)
And 2 have to use Descartes' rule of signs to state how many positive real zeros and how many negative real zeros f(x) might have.

Im having trouble with the Descartes' rule!

We're no strangers to love

You know the rules and so do I

A full commitment's what I'm thinking of

You wouldn't get this from any other guy

I just wanna tell you how I'm feeling

Gotta make you understand

Never gonna give you up

Never gonna let you down

Never gonna run around and desert you

Never gonna make you cry

Never gonna say goodbye

Never gonna tell a lie and hurt you

We've known each other for so long

Your heart's been aching but you're too shy to say it

Inside we both know what's been going on

We know the game and we're gonna play it
