一个“整式的乘法”的问题请先阅读下列解题过程,再仿做下面的问题.已知X*X + X - 1=0,求X*X*X + 2*X*X + 3的值.解X*X*X + 2X*X +3=X*X*X +X*X -X +X*X +X +3=X{X*X +X -1} +X*X +X -1 +4=0+0+4=4+ x + X*X + X*X*X=0.+ X*X + X*X*X
7.72-X=1.8(X+0.
x-1.8=1/2x+0.
3.6x*(2.1-x)=4.8x
(X+X)+(X-X)+(X*X)+(X/X)=100
1.8x-x=2.4x=?
40%x+70%x-x=1.8
(x-8.2+10.8)/2=1.8 和 3.6x-x-0.1x=0.75
(x-8.2+10.8)/2=1.8 和 3.6x-x-0.1x=0.75
x^2+3x-1.8=x x=?
