$M = \frac{ {x}^{2} + x - 2 }{ {x}^{2} + 2x - 3 } + \frac{ {x}^{2} + 7x + 12}{ {x}^{2} + 6x + 9 } \\ M = \frac{(x + 2)(x - 1)}{(x + 3)(x - 1)} + \frac{(x + 3)(x + 4)}{(x + 3)(x + 3)} \\ M = \frac{(x + 2)}{(x + 3)} + \frac{(x + 4)}{(x + 3)} \\ M = \frac{x + 2 + x + 4}{x + 3} \\ M = \frac{2x + 6}{x + 3} \\ M = \frac{2(x + 3)}{(x + 3)} \\ M = 2$
