(35 -5x)/10
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
(2x-2)(x-1)=0 x(x-5)=5x-10
1)x+1/x=3,求x^10+x^5+1/x^5+1/x^10的值
(x-6)/(x-5)-(x-7)/(x-6)=(x-9)/(x-8)-(x-10)/(x-9)
计算:1/(x^2-7x+10)+1/(x^2-x-2)+1/(x^2+5x+4)+1/(x^2+11x+28)=( )
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
解方程:(x+2)·(4x-5)=4x·x+35
当X=5时,4X+3X()35,4+3X()35.
X-2/5X-[(X-2/5X)*5/9-10]=74
因式分解(x²+5x)²+10(x²+5x)+24
因式分解10x^2+5x是等于5x(2x+1)吗
