The matches are:
- Equation 1: No match
- Equation 2: \([2, -4]\)
- Equation 3: \([4, -3]\)
- Equation 4: \([3, -4]\)
Thus, the final answer is:
\[
\boxed{
\begin{align_}
\text{Equation 1: No match} \\
\text{Equation 2: } x = 2 \text{ or } x = -4 \\
\text{Equation 3: } x = 4 \text{ or } x = -3 \\
\text{Equation 4: } x = 3 \text{ or } x = -4
\end{align_}
}
\]
