(x^2+1)^2-20(x^2+1)+100因式分解(x^2+1)^2-20(x^2+1)+100因式分解(x^2+1)^2-20(x^2+1)+100因式分解(x^2+1)^2-20(x^2+1)
(x^2+1)^2-20(x^2+1)+100因式分解
(x^2+1)^2-20(x^2+1)+100因式分解
(x^2+1)^2-20(x^2+1)+100因式分解
(x^2+1)^2-20(x^2+1)+100
=[(x²+1)-10]²
=(x²-9)²
=[(x+3)(x-3)]²
=(x+3)²(x-3)²
把x^2+1先看成一个变量
(x^2+1)^2-20(x^2+1)+100
=[(x^2+1)-10]^2
=(x^2-9)^2
=[(x-3)(x+3)]^2
=(x-3)^2(x+3)^2

分解因式----(X*X-X)(X*X-X-2)+1
】x(x+1)+x^2(x-1)
1/(1-x)+1/(1+x)+2/(1+x*x)+4/(1+x*x*x*x)+8/(1-x*x*x*x*x*x*x*x)怎么做
x/2+x/8+x/12+x/20=1
因式分解(x+1)(x-2)(x-3)(x-6)+20
计算:1/x(x-1)+1/(x-1)(x-2)+1/(x-2)(x-3)+.+1/(x-19)(x-20)
x-1/x-2
{2X+1}+{X}
(x^2-1)/x
x^2-1/x
2X+|X+1|
|x-1|+|x-2|
(x+1)/(x+2)
/X+1/+/X+2/
2x/(1-x)
