SOLUTION: Given the equation x^3 - 2x^2 + x - 3 = 0, what are the possible rational roots please someone help me?

You can put this solution on YOUR website!
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 -3 (the last coefficient):



Now let's list the factors of 1 (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 possible rational zeros of the function
