已知m2+m+1等于0,求(3m2-2m)-2(m2-3/2m)+1已知m2+m+1等于0,求(3m2-2m)-2(m2-3/2m)+1已知m2+m+1等于0,求(3m2-2m)-2(m2-3/2m)

已知m2+m+1等于0,求(3m2-2m)-2(m2-3/2m)+1
已知m2+m+1等于0,求(3m2-2m)-2(m2-3/2m)+1

已知m2+m+1等于0,求(3m2-2m)-2(m2-3/2m)+1
m2+m+1=0
(3m2-2m)-2(m2-3/2m)+1
=3m²-2m-2m²+3m+1
=m²+m+1
=0

0-

(3m2-2m)-2(m2-3/2m)+1
=3m^2-2m-2m^2+2*3/2*m+1
=3m^2-2m-2m^2+3m+1
=m^2+m+1
=0
