(2014^3+2014^2-3*2014-2)分之(2014^3-2*2014^2+1) 计算,
(2014^3+2014^2-3*2014-2)分之(2014^3-2*2014^2+1) 计算,
(2014^3+2014^2-3*2014-2)分之(2014^3-2*2014^2+1) 计算,
(2014^3+2014^2-3*2014-2)分之(2014^3-2*2014^2+1)
=(2014^2-2014-1)(2014+2)分之(2014^2-2014-1)(2014-1)
=(2014+2)分之(2014-1)
=2016分之2013
设2014=x
(2014^3+2014^2-3*2014-2)分之(2014^3-2*2014^2+1)
=(x³+x²-3x-2)分之(x³-2x²+1)
=[(x³-1)+(x²-2x+1)-x-2]分之(x³-1-2x²+2)
=[(x³-1)+(x²-2x...

设2014=x
(2014^3+2014^2-3*2014-2)分之(2014^3-2*2014^2+1)
=(x³+x²-3x-2)分之(x³-2x²+1)
=[(x³-1)+(x²-2x+1)-x-2]分之(x³-1-2x²+2)
=[(x³-1)+(x²-2x+1)-(x+2)]分之[(x³-1)-2(x²-1)]
=[(x-1)(x²+x+1)+(x-1)²-(x+2)]分之[(x-1)(x²+x+1)-2(x+1)(x-1)]
=[(x-1)(x²+x+1+x-1)-(x+2)]分之[(x-1)(x²+x+1-2x-2)]
=[(x-1)(x²+2x)-(x+2)]分之[(x-1)(x²-x-1)]
=[x(x-1)(x+2)-(x+2)]分之[(x-1)(x²-x-1)]
=[(x+2)(x²-x-1)]分之[(x-1)(x²-x-1)]
=(x+2)分之(x-1)
x=2014
原式=(2014+2)分之(2014-1)
=2016分之2013
