Please help i have exams tomorrow! List possible zeros using the rational zero theorem. Could i find these by using synthetic division? Is it the same thing? -_- thanks.

    List all of the possible zeros, use synthetic division to test the possible zeros, find an actual zero, and use the actual zero to find all the zeros of x^4-5x^3+20x-16=0

    -x^3+6 x^2-6 x+y+18 = 0

    y = x ((x-6) x+6)-18

    Thanks this helps, do you think you can help me with my next one? The question is identify the number of zeros or solutions for f(x)=12x-32x^2+40-x^3 I am working on this one & the question i just asked. p.s. don't feel like you have to help me, if you r busy :)

    x^2 (32 + x) + f[x] == 40 + 12 x

    f(x)+x (x (x+32)-12) = 40

    i can't find the right factor for the synthetic division...or maybe i made a mistake.
