(1-X)^2=560/875=16/25
(1-X)=4/5
X =1/5=0.2
875 * (1-x)^2 = 560,得
(1-x)^2 = 560/875 = 16/25,得
1-x = ±根号下的16/25
x = 1±4/5,即
x = 9/5 或 x = 1/5
875乘以(1-x)的平方=560
(1-x)的平方=0.64
1-x=± 0.8
x=0.2,x=1.8
(1-X)^2=560/875=16/25
(1-X)=±4/5
X1=1/5
X2=9/5
875乘以(1-x)的平方=560
(1-x)²=560/875=0.64
1-x=±0.8
x1=0.2,x2=1.8
(1-x)的平方=560/875
1-x=4/5
x=1/5
