DRS says there are
2 or 0 positive roots
1 negative root
RZT says look for roots among ±1,5,7,35
Synthetic division using easy values first says
f(x) = (x-1)(x^2-2x-35)
I think you can probably take it from there, ok?
Find all the zeros of the polynomial function by using the Rational Zero Theorem, Descartes Rule of Signs and Synthetic Division.
f(x)=x^3-3x^2-33x+35
