计算:-1^2006-8(3.14-2)^0+(-1/2)^-2*2
(3x-2y)^2-(y+3y)(3x-y)
分解因式:
(1) x^3-4x (2) y^3-4y^2+4y
诺a-b=2,3a+2b=3,则3a(a-b)+2b(a-b)=___________

-1^2006-8(3.14-2)^0+(-1/2)^-2*2
=-1-8×1+(-2)^2*2
=-1-8+8
=-1
(3x-2y)^2-(y+3x)(3x-y)
=9x^2-12xy+4y^2-9x^2+y^2
=-12xy+5y^2
(1) x^3-4x
=x(x^2-4)
=x(x+2)(x-2)
(2) y^3-4y^2+4y
=y(y^2-4y+4)
=y(y-2)^2
诺a-b=2,3a+2b=3,
3a(a-b)+2b(a-b)
=(3a+2b)(a-b)
=3×2
=6

2x-x/2<-3/2
