(1)/((x-5)(x+4)

Explanation:

first factor out the equations with the x^2 in the first bottom equation, you'll get: (x-5)(x+2) the second equation: (x+4)(x-3) you can see that in both equations, two factor cancel each other out. so once it does, you're left with nothing on top so you have to put a one on top
