\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-------------------------------\\\\

\bf \cfrac{x^2}{x^2-4}-\cfrac{x+1}{x+2}\implies \cfrac{x^2}{x^2-2^2}-\cfrac{x+1}{x+2}\implies \cfrac{x^2}{(x-2)(x+2)}-\cfrac{x+1}{x+2}
\\\\\\
\textit{so, then the LCD will just be }(x-2)(x+2)
\\\\\\
\cfrac{x^2-(x+1)(x-2)}{(x-2)(x+2)}\implies \cfrac{x^2-(x^2-x-2)}{(x-2)(x+2)}\implies \cfrac{\underline{x^2-x^2}+x+2}{(x-2)(x+2)}
\\\\\\
\cfrac{\underline{x+2}}{(x-2)\underline{(x+2)}}\implies \cfrac{1}{x-2}
