x(x-1)/2=182怎么算?

x(x-1)/2=182怎么算? x(x-2)+m(1-x)=3怎么算 X/2+X/1+X/4=14,求X,具体怎么变形怎么算呢 (x+2)(x+3)-(x+6)(x-1) 怎么算? x*x+2*x+1=36,x怎么解, (x^10-x^5+1)/(x^2+x+1) 怎么算?(x^10-x^5+1)/(x^2+x+1)=（x^8-x^7+x^5-x^4+x^3-x+1) (2x-1)(2x+1)+3(x+2)(x-2)=(7x-1)(x+1)怎么算? 下列函数中,不满足f(2x)=2f(x)的是 A f(x)=|x| B f(x)=x-|x| C f(x)=x+1 D f(x)=-x 怎么几个都怎么算 [(x+12)^1/2]-x=2x-8 算x怎么算? x+1分之x-1 + 1-2x分之2x=0怎么算, （x-1)(1-2x)+2x(x+1)=0~怎么算耶~ 2/x+2/(x+3)+(x-2)/(x+3)=1怎么算 一元二次方程(x^2+x)(x^2+x-2)+1=0怎么算 x²+2x-6/x²+2x=1怎么算 (2x+1)²-(x+3)(3-x)=6x怎么简便算? x乘(x+1)乘(x+2)乘(x+3)=360怎么算 255+2%X+5.55%X+1%X=X 怎么算 x(x+1)(x+2)(x+3)=3024怎么算呀
