# Increasing spacing between the rows of a table containing both equations and words

Below is some code I am working with.

\begin{tabular}{l|m{4.75in}}
Equation 1 & $y^{10} + x^{6} + 7x^{3} + 6y^{11}$\\\hline
Equation 2  & \begin{alignedat}{1}(n + 1)^{2}u_{n + 3} &+ (n^{4} + 4n^3 + 3n^{2} + 2n + 1)u_{n + 2} + (5m^{9} + 6m^{7} + m^{6})u_{n + 1} + p^{7} \\&+ (n^{20} + n^{19} + n^{18} + n^{17} + n^{16} + n^{15} + 5n + 2)u_{n + 10}\end{alignedat}\\\hline
Notes & This is some equation\\\hline
\end{tabular}

How does one increase the vertical spacing between Equation 1 and Equation 2? In the output the top of Equation 2 touches the horizontal line from the bottom part of Equation 1. I've tried \renewcommand{\arraystretch}{1.5} but that doesn't seem to work with the alignedat environment. Since I have many of these tables with similar code, it would also be nice if I didn't have to go through each one manually.

\begin{aligned} \smash[b]{\vphantom{\bigg|}} (n + 1)^{2}u_{n + 3} &+ (n^{4} + 4n^3 + 3n^{2} + 2n + 1)u_{n + 2} + (5m^{9} + 6m^{7} + m^{6})u_{n + 1} + p^{7} \\ &+ (n^{20} + n^{19} + n^{18} + n^{17} + n^{16} + n^{15} + 5n + 2)u_{n + 10} \smash[t]{\vphantom{\bigg|}} \end{aligned}\\\hline
