Answer:

\frac{x + 7 }{x - 3}

Step-by-step explanation:

First factorize both expressions

\frac{ {x }^{2} + 11x + 28 }{x { }^{2}  + x - 12}  \\  \frac{x {}^{2 } + 7x + 4x + 28 }{x { }^{2} + 4x - 3x - 12 }  \\   \frac{x(x  + 7) + 4(x + 7)}{x(x + 4) - 3(x + 4) }  \\  \frac{(x  + 7)(x + 4)}{(x + 4)(x - 3)}

Now you can cross out x+4

and you'll be left with

\frac{x + 7}{x  - 3}
