t？ /4-t+ 1=(t/2- 1)？ , you are not mistaken, that's it!

Then the absolute value of AB = (t/2- 1), why is it not derived?

t=ab，a & lt 1，b & lt 1，t

Finding the minimum value of ab is equivalent to finding the maximum value of T here, that is, finding the maximum value of AB, right?

(a-b)? "0, right? Answer? +b？ 2ab, in short, if and only if a=b, get!

You can find it in 3 seconds by substituting it into the formula!

You can get the first half if you do it right! I just can't do it anymore! The completely flat way is not well mastered!
