8x-12.4=16(X-2.4)
8x-12.4=16(X-2.4)
8x-12.4=16(X-2.4)
8X -12.4=16X-38.4
8X-16X=12.4-38.4
-8X=-26
X=3.25
8x-12.4=16(x-2.4)
8x-12.4=16(X-2.4)
x的平方+( )x+16=(x+ )(x+8)
问几道解方程x/6-x=(x-3)/6x-1=1/2x+1/4x+1/8x+1/16x+1/32x77/x=2.5*77/x+2.4要注明是哪一题
10x+2(x+4)=8x+16
x-x/5=2.4 (求未知数x) 12÷5%x=8 4x+x=12.5
X²-8X+16 =(X-4)² 、X²+X+1=X(X+1+1/X)哪个是因式分解?
X+(X+8)+(X+16)=96X=24
(x^2-4x)/x^2-8x+16
(16x^4+4x^2+x)/x=?
(x+x^-1)(x^2+x^-2)(x^4+x^-4)(x^8+x^-8)(x^16+x^-16)(x^2-1)=?

matlab解数值分析题p=(x-1)*(x-2)*(x-3)*(x-4)*(x-5)*(x-6)*(x-7)*(x-8)*(x-9)*(x-10)*(x-11)*(x-12)*(x-13)*(x-14)*(x-15)*(x-16)*(x-17)*(x-18)*(x-19)*(x-20)解为1,2,3……,20取多个非常小的数用软件工具求解方程p(x)+n*x^19=0,并
x/x-2=x²-8x+16/x²²-4x+4
x=1-x/2+x/4-x/8+x/16-x/32
(x+x)+(x-x)+(x/x)=11.2
