SUMMARY
The discussion focuses on the method of partial fraction decomposition, specifically for the expressions $$\frac{3x+4}{x^2+3x+2}$$, $$\frac{5x^2+5x+8}{(x+2)(x^2+2)}$$, and $$\frac{x^2+15x+21}{(x+2)^2(x-3)}$$. The first example is solved by factoring the denominator into $(x+1)(x+2)$ and expressing the fraction as $$\frac{2}{x+2}+\frac{1}{x+1}$$. This method is essential for simplifying rational functions in calculus and algebra.
