find the inverse

Question

  2   +1 

x+2

 

Answer 1

The inverse of a number is its reciprocal.  If it is a whole number with no obvious denominator give it a 1 as the denominator.

 

I suppose you're are trying to find the inverse of 3 different things here 2, +1, and x + 2

 

2/1 is the same as 2 so the inverse is 1/2

 

You can do the same with the others, even x+2

 

(x+2)/1 inverse = 1/(x+2)

 

If this wasn't what you were looking for perhaps there is more information you can add.
