\(x^2+5y^2-4xy-x+2y-6=0\)
\(\Leftrightarrow x^2-4xy+4y^2-\left(x-2y\right)-6=-y^2\)
\(\Leftrightarrow\left(x-2y\right)^2-\left(x-2y\right)-6=-y^2\le0\)
\(\Leftrightarrow\left(x-2y+2\right)\left(x-2y-3\right)\le0\)
\(\Leftrightarrow-2\le x-2y\le3\)

Huy Toàn 8A (TL) 13/10/2018 at 07:01We have:
1755 . 2 = 3510 6019 . 2 = 12038
1755 + 3510 = 4265 6019 + 12038 = 18057
The answer is :
8426 . 2 = 16852
8426 + 16852 = 25278
=> ? = 25278
