Use quadratic functions. Suppose that the cost function for a particular item is given by the equation

$C\left(x\right)=2{x}^{2}-320x+12,920$ ,

where x represents the number of items. How many items should be produced to minimize the cost?

Solving a system of inequalities in modulo N

I have a problem that boils down to two unknowns, ${X}_{1}$ and ${X}_{2}$, where:

${X}_{1}\cdot M+AmodN={X}_{2}$

And:

${X}_{1}<{L}_{1}modN$

${X}_{2}<{L}_{2}modN$

Making a Quadratic Function spit out Integer Outputs for Rational Inputs

Suppose I have a quadratic function

$f\left(x\right)=a{x}^{2}+bx+c,a,b,c\in \mathrm{\mathbb{Z}}$

and I want to find rational (non-integer) values of x for which $f\left(x\right)\in \mathbb{Z}$.
