Simplify the products: `(x^2+2x+2)(x^2-2x+2)`

Explanation

Given:

`=> (x^2+2x+2)(x^2-2x+2)`

`=> ( x^2+2+2x)(x^2+2-2x)..............(1)`

Using the identity in (2) equation ,we get

`(a-b) (a+b)=(a^2-b^2)`

`=> [( x^2+2)+2x)(x^2+2)-2x)]`

`=> ( x^2+2)^2-(2x)^2....................(2)`

Again,Using the identity
