Show that (1+x)2 can be more accurately determined from (x+2)x + 1
Now in (1+x) squared you have to perform 2 multiplications.
In (x+2)x + 1 you perform 1 multiplication and one addition.
Why is one multiplication and one addition better than the square of (x+1)
There is no way of saying that will be more accurate than without saying what kinds of errors you are talking about. And that may depend upon what numbers x is close to.
