Để biểu thức 2016 : (2017 - a) có GTLN
\(\Leftrightarrow\)2017 - a có GTNN, 2017 - a ≠0
\(\Leftrightarrow\) 2017 - a = 1
\(\Leftrightarrow\)a = 2016
De bieu thuc 2016 : ( 2017 - a ) co GTLN
\(\Leftrightarrow\)2017 - a co GTNN, 2017 - a \(\ne\)0
\(\Leftrightarrow\)2017 - a = 1
\(\Leftrightarrow\)a = 2016
