You would subtract each term of g(x) from f(x)

f(x) = 9x^3 + 2x^2 - 5x + 4
g(x) = 5x^3 - 7x + 4

9x^3 - 5x^3 = 4x^3

2x^2 - 0 = 2x^2

-5x - (-7x) = 2x

4 - 4 = 0

FINAL ANSWER:
4x^3 + 2x^2 + 2x

The remaining parts are 1/3 of one pie and 5/6 of the other pie.

To find how much pie is remaining, we just need to sum those fractions.

\frac{1}{3}+\frac{5}{6}=\frac{6+15}{18} =\frac{21}{18} =\frac{7}{6}

Therefore, there remains 7/6 of pie. They ate just 1/6.
