Find 2 numbers a and b such that (a-b)^2 < (a+b)(a-b)< (a+b)^2 find two numbes a and b such that this is not true

Suppose for the moment that the inequality holds for all :

Expanding everything gives

In particular, the inequality says that for any choice of . But if and , then while .

So one possible choice of could be and . Then we get

but clearly it's not true that .

we need the options

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
