改变方程的参考

Question

我找到了新的方法来最佳地创造一些参考到主方程，然后到子方程。到目前为止，我已经写了大约 200 页的免费学生书，我想对已经写好的方程和子方程做一些修改，但这样更简单。最大的问题是更改他写方程解释部分的所有参考文献，这让我心情很不好。有没有办法自动更改参考文献？我举一个小例子：

\documentclass{article}
\usepackage[english,italian]{babel}
\usepackage{amsmath}
\usepackage[colorlinks]{hyperref}
\usepackage{lipsum}

In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others.[1]

Given a general quadratic equation of the form 

\begin{subequations}
    \begin{equation}
        ax^2+bx+c=0 \label{eq10a}
    \end{equation}
\end{subequations}

with x representing an unknown, \textit{a}, \textit{b} and \textit{c} representing constants with $a\neq  0$, the quadratic formula is:

\begin{subequations}[resume]
    \begin{equation}
        x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\label{eq10b}
    \end{equation}
\end{subequations}
Here are some references: \eqref{eq10a}, \eqref{eq10b}

要更改参考文献，我应该使用“查找”，这项工作太长且繁琐，有没有办法拥有一个标签数据库，并且可以在数学解释的书面部分自动更改？
