若单项式M,N满足2x（M+3x）=6*x*x*y*y+N,求M,N
若单项式M,N满足2x（M+3x）=6*x*x*y*y+N,求M,N
2x(m+3x)
=2xm+6x²
=6x²y²+n
所以2xm=6x²y²
6x²=n
所以
m=3xy²
n=6x²
已知,单项式M,N满足2x(M+3x)=6x^2y^2+N,求M,N. 已知单项式M、N满足2x(M+3x)=6x^2y^2+N,求M、N. 已知单项式M,N满足3x(M-5x)=6x^2y^3+N,求M,N 已知,单项式M,N满足2x（M+3x)=6x²y²+N,求M,N 已知单项式M N满足3x(M-5x)=6x^2y^2 求M N 已知单项式M、N满足2x(M+3x)=6x^2y^2+N,求MN 已知单项式M,N满足3x(M-5x）=6x²y²+N,求MN. 已知:单项式M,N满足2x(M+3x)=6x的2次方y的2次方+N,求M,N 已知:单项式M,N满足2x(M+3x)=6x^2y^2+N,求M,N的值. 已知单项式M,N满足等式3x(M-5x)=6x^2y^3+N.求M,N. 已知单项式M、N满足等式：2x(M-x）=6x²y三次方+Nx²,求M、N. 已知单项式M、n满足等式3x（m-5x）=6X^2Y^3 N,则m=
