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
（X+X)+(X-X)+(X*X)+(X/X)=100
x-0.48x=7.28
x-0.48x=4.68
x-0.52x=0.48
X-0.48X=0.78
x-0.48x=20.8
x-0.48x=7.2
x-0.48x=7.28
16^X - 12^X -9^X = 0.求X.
(98-X)+(100-X)+X=X/0.
