Which statement is always true if a quadratic polynomial has rational coefficients and one zero is (\sqrt{13})?

The other zero will be (-\sqrt{13})

For rational coefficients, the conjugate (-\sqrt{13}) of (\sqrt{13}) also appears when the linear coefficient is rational. This follows from (a+\sqrt{b}) and (a-\sqrt{b}).
