Using the rational zeros theorem to find all zeros of a polynomial

The function below has at least one rational zero. Use this fact to find all zeros of the function

if more than one zero, separate with commas. Write exact values, not decimal approximations

+-(1,7)/(1,5)=+-1/(5,1)

1. Assuming you meant

g(x) = (5x^3 - 28x^2 - 48x)/(-8x+7)

it's not a polynomial. The possible rational zeroes of the numerator include all the fractions whose numerator is a factor of 48 and whose denominator is 1 or 5.

The only rational root of that is 0.

Would you care to repost the question, using ^ for exponents, as I did above?
