已知x=3+2√2,y=3-2√2,求x²y+xy²的值已知x=3+2√2,y=3-2√2,求x²y+xy²的值已知x=3+2√2,y=3-2√2,求x

已知x=3+2√2,y=3-2√2,求x²y+xy²的值
已知x=3+2√2,y=3-2√2,求x²y+xy²的值

已知x=3+2√2,y=3-2√2,求x²y+xy²的值
x^2y+xy^2
=xy(x+y)
=(3+2√2)(3-2√2)(6)
=(9-8)(6)=6

知x=3+2√2,y=3-2√2,求
xy = 9 - 8 = 1
x +y = 3 +3 = 6
x²y+xy²
= xy (x +y )
= 1 x 6
= 6
