Answer:

Option 2 is correct that is \frac{x+2}{x+9}  and x\neq-9and x\neq-12

Step-by-step explanation:

We have been given with the expression \frac{x^2-10x-24}{x^2-3x-108}

We will simplify  the given expression by factorisation we will get \frac{x^2-12x+2x-24}{x^2-12x+9x-108}  

Taking x as common from first two terms in numerator and 2 from last two terms in numerator

Similarly, take x common from first two terms and 9 from last two terms in denominator we will get

\frac{x(x-12)+2(x-12)}{x(x-12)+9(x-12)}

After arranging the terms we will get \frac{(x+2)(x-12)}{(x+9)(x-12)}

Taking out the common factor which is (x-12)  from numerator and denominator it will get cancelled we will get

\frac{(x+2)}{(x+9)}

Hence, Option 2 is correct that is \frac{x+2}{x+9}  and x\neq-9and x\neq-12
