Question

How do you simplify `x- 1- \frac { 2} { x + 1}`?

Answer 1

`color(indigo)(=> (x^2 - 3) / (x + 1)`

Explanation:

`(x - 1) - (2 / (x + 1))`

`=>(((x-1) (x + 1)) - 2) / (x = 1), " taking L CM as " (x + 1)`

`=> (x^2 - 1 -2) / (x + 1), " Multiplying after removing brackets"`

`=> (x^2 - 3) / (x + 1), " simplifying"`
