x/80+3=x/50

3x*x=1600+x*x-80x x+3x+x-2+x+x+50%x=188 求x 80(x-6)=50(x+3) x/80 +6=x/50 -3 x/80+3=x/50 80+x=(56-x)*3 x=x (x+x+23+x+50)=3x 怎么解 (x+1)+(x+2)+(X+3).+(x+50)=1325 x+ x+(x*50%)=1.5X? 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!)+. 解方程,亲们帮帮忙!2／3＋50％x＝1.6 x＝?x-40%x=0.96 x=?4/5x-1/2x=6.4 x=?80%x-0.6x=0.12 x=?1/2(x-80%)=0.6 x=?4(x+1/4)=16 x=?40%+20%x+7.2 x=?5/6(x-40%)=2 (X+1)X(X+2)X(X+3)=504 一个“整式的乘法”的问题请先阅读下列解题过程,再仿做下面的问题.已知X*X + X - 1=0,求X*X*X + 2*X*X + 3的值.解X*X*X + 2X*X +3=X*X*X +X*X -X +X*X +X +3=X{X*X +X -1} +X*X +X -1 +4=0+0+4=4+ x + X*X + X*X*X=0.+ X*X + X*X*X 80%X*(1+50%)=10+X 求X是多少? 80/x-3=80/1.12x x等于多少 =(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 (3x-5)*(4x-3)=80 求x
