(120-50x)/5=(50x-5x)/(50+5)+(120-50x)/50 求结果

X-X/12-X/7-X/8-X/4-X/20-X/5-30-120-300=50解方程 x+ x+(x*50%)=1.5X? 10x+2x*[(50-x)/2]+5x[(50-x)/2]=240 求文档:解方程：x-x/12-x/7-x/8-x/4-x/20-x/5=30+120+300+50 初一1道解方程,步骤要详细X/12+X/7+X/8+X/4+X/20+X/5+30+120+300+50=X 用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+. 50X+(50-5)(X+1)=425,x=? =(x^2-5x)^2+10(x^2-5x)+24 =x^4-10x^3+25x^2+10x^2-50x+24 这是怎么转化的(X-1)(X-2)(X-3)(X-4) =(X-1)(X-4) (X-2)(X-3)=（x^2-5x+4)(x^2-5x+6)=(x^2-5x)^2+10(x^2-5x)+24=x^4-10x^3+25x^2+10x^2-50x+24=x^4-10x^3+35x^2-50x+24 =（x^2-5x+4)(x^2-5x+6) =(x^2-5x)^2+10(x^2-5x)+24 是怎么转化的(X-1)(X-2)(X-3)(X-4) =(X-1)(X-4) (X-2)(X-3)=（x^2-5x+4)(x^2-5x+6)=(x^2-5x)^2+10(x^2-5x)+24=x^4-10x^3+25x^2+10x^2-50x+24=x^4-10x^3+35x^2-50x+24不好意思我弄错了，是=（x^2-5 5x^-15x=50除以5x 解方程：60%x+5+50%x-25=x x-5%x-50%x×60%=36解方程 5(x/10+x/12)=x-50怎么解 2x+8-10x+50=5x-10 证明(x+1)(X+3)(x+5)(x+7)+15=(X+8x)+22(x+8x)+120 1.2x-5=x+5 1.2x-x=5+5 0.2x=10 x=50 化简求值 x/x-5+50/25-x^-x+1/5+x,其中x=3. 4x+5=50 x=
