(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

trying to prove left-hand side = right-hand side

this is where i'm stuck:

[tex]

1 - [1 / (x+1)!] + [(x+1) / (x+2)!] = 1 - [1 / (x+2)!]

[/tex]

2. Relevant equations

3. The attempt at a solution

i tried this but can't get anywhere

get a common demoninator:

1 - [(x+2)! + (x+1)*(x+1)! / (x+1)!*(x+2)!]

anyone seeing what i'm not seeing?
