Question
Fine the product mentally. [(x+1) (x1)^2
2 Answer

1. User Answers mikikiki
If the product is: [(x+1) (x1)]^2 , the answer is:
[(x+1) (x1)]^2 = [x^21]^2 = x^42x^2+1

Answer:
x^4  2x^2 +1
Stepbystep explanation:
[(x+1) (x1)]^2
We notice that this is the difference of squares
a^2 b^2 = (a+b) (ab)
Since we have (x+1) (x1) , it simplifies to (x^2 1)
[x^21]^2
We know (ab)^2 is a^2 2ab +b^2
[x^21]^2 = x^4  2x^2 +1
