: rule of signs to state the numbier of possible positive and negative real zeros of each polynomial function
P(x)=10x6 -9x5 -14x4 -8x3-18x2+x+6
I used my calculator to find the possible zeros and I understand there are 6 possible zeros
so far x=-1,-.6, .5, 2

Possible Zeros:
Any rational zero can be found through this equation
where p and q are the factors of the last and first coefficients
So let's list the factors of 6 (the last coefficient):
Now let's list the factors of 10 (the first coefficient):
Now let's divide each factor of the last coefficient by each factor of the first coefficient
Now simplify
These are all the distinct rational zeros of the function that could occur
