-(x+2)?^2+16(x-1)^2怎么做?
-(x+2)?^2+16(x-1)^2怎么做?
-(x+2)?^2+16(x-1)^2怎么做?
-(x+2)^2+16(x-1)^2
=16(x-1)^2-(x+2)^2
=[4(x-1)-(x+2)][4(x-1)+(x+2)]
=(4x-4-x-2)(4x-4+x+2)
=(3x-6)(5x-2)
=3(x-2)(5x-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-2)+16 (x-1)(x-2)+3x(x+3)-4(x+2)(x-3)(x+2)(x-2)+16 (x-1)(x-2)+3x(x+3)-4(x+2)(x-3)
计算(x+/1x)(x^2+1/x^2)(x^4+1/x^4)(x^8+1/x^8)(x^16+1/x^16)(x^2-1)
(x+1/x)(x^2+1/x^2)(x^4+1/x^4)(x^8+1/x^8)(x^16+1/x^16)(x^2-1)
(x+x^-1)(x^2+x^-2)(x^4+x^-4)(x^8+x^-8)(x^16+x^-16)(x^2-1)=?
解方程:2x(x-2)-6x(x-1)=4x(1-x)+16
(x+1)(x^2+1)(x^4+1)(x^8+1)(x^16+1)(x-1)
x=1-x/2+x/4-x/8+x/16-x/32
x-1/x-2
{2X+1}+{X}
(x^2-1)/x
x^2-1/x
2X+|X+1|
