m^2-5mn+6n^2=0
(m-2n)(m-3n)=0
m=2n或m=3n
m/n+n/m=2+1/2=5/2
或者m/n+n/m=3+1/3=10/3
已知实数m,n,且m>n>0,m²+n²=4mn,则m²﹣n²/mn的值等于∵(m+n)²=m²+2mn+n²,(m-n)²=m²-2mn+n²,m²+n²=4mn.(m+n)²=6mn(m-n)²=2mn(m+n)²(m-n)²=12m²n²mm³-2m
已知mn-n=15,m-mn=6,则m-n=_,-2mn+m+n=_
已知mn-m=15,n-mn=6则n-m=( ),-2mn+m+n=( )
已知m+n=5 mn=-14则m^2n+mn^2=
