Expand ( x - 1/x^2)^4

We want to expand the expression:

We can just do it by brute force, this is:

First, rewrite our expression as the product of two square factors:

Now we can expand each one these two factors:

That can be simplified to

Now we can replace that in our original expression to get:

Now we can expand that last product, to get:

We can simplify that to:

That is the expanded expression.

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
