75%x+35=90%-1075%x+35=90%-1075%x+35=90%-10转化得:0.75x+35=0.9-100.75x+35=-9.10.75x=-9.1-350.75x=-44.1x=
75%x+35=90%-10
75%x+35=90%-10
75%x+35=90%-10
转化得:0.75x+35=0.9-10
0.75x+35=-9.1
0.75x =-9.1-35
0.75x =-44.1
x =-44.1/0.75(计算器)
是90%x吗?
[75%x- (x-90)]×10=[(x-70)-(x-90)]×15
75%x+35=90%-10
x+2x+(x+10)=90,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
