When x=_ Time division formula 2x & # 178; + 8x + 11 / X & # 178; + 4x + 5 Value_ Is the fraction (2x & # 178; + 8x + 11) / (X & # 178; + 4x + 5) To 2 + 1 / X & # 178; + 4x + 5 How can x = 1 and fraction equal to 30???

After changing to 2 + 1 / (x ^ 2 + 4x + 5), because x ^ 2 + 4x + 5 = (x + 2) ^ 2 + 1 has a minimum value of 1,
Therefore, when x = - 2, the original formula has a maximum value of 2 + 1 = 3

Ln (1 + 1 / x) uses Taylor's formula to find the limit

You have to give the direction of the limit!
