x(0.5-x)=0.06过程和结果

把左边移项到右面~

得到x^2-0.5x+0.06=0

那么分解因式(x-0.2)(x-0.3)=0

所以x=0.2或者0.3

加油!祝你成功!

0.5x-x^2=0.06
x^2-0.5x+0.06=0
(x-0.25)^2=0.0625-0.06=0.0025=0.05^2
x-0.25=±0.05
x=0.25±0.05
x=0.3,x=0.2

x(0.5-x)=0.06
100x(0.5-x)=6
100x^2-50x+6=0
(10x-3)(10x-2)=0
x1=3/10
x2=2/10=1/5

x(0.5-x)=0.06
=>0.5x-x^2=0.06
=>x^2-0.5x+0.06=0
=>x^2-0.5x+0.0625=0.0025
=>(x-0.25)^2=0.05^2
=>x-0.25=0.05或-0.05
=>x=0.3或0.2

x(0.5-x)=0.06
0.5x-x^2-0.06=0
x^2-0.5x+0.06=0
(20x-6)(5x-1)=0
x=3/10 x=1/5
