M=2\(x^4\)+3\(x^2y^2\)+\(y^4\)+2\(y^2\)
M= (2\(x^4\)+ 2\(x^2y^2\)) +(\(x^2y^2\)+\(y^4\))+2\(y^2\)
M=2\(x^2\)(\(x^2\)+\(y^2\))+\(y^2\).(\(x^2\)+\(y^2\))+2\(y^2\)
M=2\(x^2\).2+\(y^2\).2+2\(y^2\)
M=4\(x^2\)+4\(y^2\)
M=4.(\(x^2\)+\(y^2\))
M=4.2=8
vậy M=8
Bạn ơi cái chỗ đoạn \(2x^2\left(x^2y^2\right)+y^2.\left(x^2y^2\right)+2y^2\) ĐOạn đó bạn khi rõ ra cho mk tách kiểu j để được như vậy ko b.Chỗ đó mk ko hiểu
(2\(x^4\)+2\(x^2\)\(y^2\)) +(\(x^2\)\(y^2\)+\(y^4\))+2\(y^2\)
=(2.\(x^2\).\(x^2\)+2\(x^2\).\(y^2\))+(\(x^2\).\(y^2\)+\(y^2\).\(y^2\))+2\(y^2\)
=2\(x^2\).(\(x^2\)+\(y^2\))+\(y^2\).(\(x^2\)+\(y^2\))+2\(y^2\)
