# How to solve a linear equation within a field of rational functions?
I have a field of rational functions over the rational numbers in 4 variables:
K = Frac(PolynomialRing(QQ,'x,y,z,w'))
and some explicit elements R[0],...,R[n] in K. Is there a way to solve the equation
a[0]R[0] + ... + a[n]R[n] == 0

Proof of Quasiconcavity of Utility Function
How can I show that the function $$u(x_1,x_2)=(x_1x_2)^\alpha$$ is quasiconcave, given $$\alpha>1,x_i\geq0$$?
I managed to find the bordered Hessian, whereby
$$(-1)^1B_1=\alpha^2(x_1x_2)^{2(\alpha-1)}x^2_2\geq0$$

$$(-1)^2B_2=0\geq0$$.

Lesson
Dynamic Programming is when you save the results of your recursion in memory. This lets you avoid making the same function calls multiple times. We haven't had to use Dynamic Programming so far, but you need it in certain problems.
