若x+y=5,xy=6,求x2y+xy2的值若x+y=5,xy=6,求x2y+xy2的值若x+y=5,xy=6,求x2y+xy2的值x^2y+xy^2=xy(y+x)=6*5=3030303024x^

若x+y=5,xy=6,求x2y+xy2的值
若x+y=5,xy=6,求x2y+xy2的值

若x+y=5,xy=6,求x2y+xy2的值
x^2y+xy^2
=xy(y+x)
=6*5
=30

30

30

30

24

x^2×y + xy^2 = xy(x+y) = 6×5 = 30

24或者30.。。

联立方程组
x+y=5
xy=6 解得;x=2.y=3 或x=3..y=2
