x²+2x+m=[x+n][x+10],则m=____,n=____x²+mx+14=[x+2][x+n],则m=____,n=_____x²+2x+m=[x+n][x+

x²+2x+m=[x+n][x+10],则m=____,n=____ x²+mx+14=[x+2][x+n],则m=____,n=_____
x²+2x+m=[x+n][x+10],则m=____,n=____ x²+mx+14=[x+2][x+n],则m=____,n=_____

x²+2x+m=[x+n][x+10],则m=____,n=____ x²+mx+14=[x+2][x+n],则m=____,n=_____
x²+2x+m=[x+n][x+10]
n+10=2
10n=m
所以n=-8
m=10n=-80
x²+mx+14=[x+2][x+n]
2+n=m
2n=14
所以n=7
m=2+n=9
