Question

11. Expand the squares of the following 1-x+ 1/x​

Answer 1

Step-by-step explanation:

Complete the multiplication on the expression on the right to get the expression on the left.

If you know the Polynomial remainder theorem already, you would observe that x2−1=0 is satisfied when x=±1 .

You can rewrite the expression on the left as x2−x+x−1 and then break it into factors, as another answer demonstrates.
