She used wrong common denominator.

<h3> Correct solution:</h3>

\frac{x}{{x}^2-5x+6} + \frac{3}{x+3}\\\\=\frac{x}{{x}^2 - 3x - 2x + 6} + \frac{3}{x+3}\\\\=\frac{x}{(x-3)(x-2)} + \frac{3}{x+3}\\\\=\frac{x(x+3) + 3(x-2)(x-3)}{(x-3)(x-2)(x+3)}\\\\=\frac{{x}^2 + 3x + 3{x}^2-15x + 18}{(x-3)(x-2)(x+3)}\\\\= \frac{4{x}^2 -12x + 18}{(x-3)(x-2)(x+3)}\\\\= \frac{2(2{x}^2 - 6x + 9)}{(x-3)(x-2)(x+3)}
